2:12 am
backyard. you know your neighbors, you know everyone in town. my dad owned a hardware store. >> that's where mark met kathy's grandmother. a customer at the store. one day when she dropped by for a visit, he met kathy. a couple of months later -- >> the kids go, marks here! i said mark who. >> he -- he sat in the back of his vehicle and he was -- singing to gabby. >> serenading her? >> yes. >> they started dating. a few years later in 1977, they got married. he was 21. she was 18. they held their wedding in a catholic church. but by then, they had umbrage and evangelical faith. and it turns out the quiet
2:13 am
young man had big ambitions. he wanted to be a doctor. kathy worked to put mark through meds school. things were tight. >> were you happy in those years? >> definitely. >> you had two boys? >> that is correct. >> nathan and aaron were born right as mark was beginning his practice. >> we were the family you would give hugs and kisses every morning and when you went to bed. when you left school. or when you are going out with your friends. we were always kissing them, we were close family. >> they moved to lima in 1990. by then, the christian faith had become very important to mark. they joined a church. >> what was it about this particular church that you both thought was -- >> two things, one of them was that the people there were friendly. the other thing was that the pastor was correctly preaching
2:14 am
god's word. and they had a very active children's program, or youth program. >> mark and kathy in the boys -- >> at the time, mark's practice was great. after those early years of doing without. the family was now well off. they took the boys on vacations, camping, europe. kathy went back to school. did some substitute teaching. life seemed to be going well for them. the next door neighbor was fond of both of them. >> mark was more reserved. very patient and caring person. would help you out and do everything for you. he had his little peculiar weighs about him. he was a little dorky. and he looked a little different from other people. until you get to know him, and then he is the most wonderful person you would ever meet. kathy was a lot of fun to be around, she was bubbly. she had an amazing laugh.
2:15 am
she loved life. just, a lot of fun. >> but, now, after 25 years of marriage. two boys, a prosperous life, kathy wang's life had ended, in one terrible morning. how did it happen? mark told investigators, he thought it was probably the water heater. so, they check that out. the allen county prosecutor was concerned by what they didn't discover. prosecutor, jurgen wall dick, -- unexplained deaths and allen county. >> we walked around the house, we looked the water heater, we looked at the other appliances, the gas furnace, the gas logs. the garage. also, the bedroom. we're kathleen wynne who died. >> they couldn't find a problem with any of the appliances. >> we just couldn't find a source. >> for the carbon monoxide? >> right. because the appliances, at that point, appeared to be working properly. >> investigators now had a
2:16 am
mystery on their hands. they return to the winger house to do some rechecking. and then, in december 2006, three months after kathy's death, mark wrangler says investigators told him, they have looked at everything. they still didn't know what had happened, he said. but, they were satisfied that it was an accident. they were settled? >> that's when i was told. >> mark was slowly trying to build a new life. but, some members of kathy's family weren't ready to move on. they were still asking questions. they thought that the answers just might lie with mark wang. >> coming up, i said, we have so many questions. nothing is being answered. >> what did kathy's family know, that made them so suspicious? >> she got in the car, your boys got in the car, mark was hanging out the side of the car, and kathy was driving away, yelling at him. >> when dateline continues.

2:19 am
2:20 am
certificate said the cause was carbon monoxide poisoning. but, what was the source? by december, 2006, three months after kathy's death, that question had grown more urgent, in the minds of her family members, and sister, diana wanted answers.
2:21 am
>> it was kind of like the white elephant in the do. none of us really want to talk about it. it -- the police weren't calling us. i felt as if nothing was getting done. >> so diana decided that she had enough. >> i actually called mom, and she actually called, the sheriff's department. >> i said, we have so many questions, and nothing is being answered. >> it wasn't just questions that kathy's family had, they also had suspicions about mark. because, they knew something. the way angler marriage was a disaster. they wanted police to know the problems went back years. >> kathy had told me, basically, mark had an affair. >> that couldn't have been easy for you sister. >> she could never forgive him for that. >> they managed to carry on, but over the years, kathy's family remembers severing tensions, that could erupt into open warfare. they say, mark thought kathy gain too much weight. she wouldn't clean the house. she's been huge amounts of
2:22 am
money. kathy got mad at mark a lot. diana recalls what happened right after they took this family portrait. mark and kathy were fighting, again. >> she got in the car, the boys got in the car, mark was hanging on the side of the car, and kathy was driving away, yelling at him. at one point, one of the boys jumped out. there was a lot of yelling in kathy left with the boys. >> mark wrangler admits that things did go downhill, after the boys love for college. he says, kathy would get deeply depressed. >> with the boys being gone, she kind of lost her purpose in life, i would say. >> were you working on it? were you trying -- >> we were in counseling. >> and then, she was gone. kathy's family knew she had been sleeping upstairs, while he was downstairs. but, then they heard when mark had told investigators. the collective alarm went off. mark said, he was sleeping with
2:23 am
a towel under the bedroom door, a fan blowing, and a bathroom window open. that was because the toilet in the master -- mark said he wanted to keep the smell out of the rest of the house. kathy's family knew about the problem with the toilet, but they figured, there was a different explanation for the towel, the fan in, the open window. they believed mark knew there was carbon monoxide in the house, because he had somehow put it there. and he was protecting himself from poisoning. >> how did you respond to that? the suspicion that was placed on you. >> i was devastated. >> five months after kathy died, her case file landed on the desk of a veteran detective, clyde bright again. >> what's your instinct? >> in reading the reports, i was sure that the water heater, the furness, and the vent, and fireplace were not the source of the carbon monoxide. so, you have to think, okay, what else in that house could
2:24 am
produce carbon monoxide? it was a generator in the garage, there were two cars in the garage, there was a snow blower in the garage. those all produce carbon oxide. >> but, of course, all those things need someone to turn them on. you don't think this is an accident? >> no. >> still, if it wasn't an accident, how could somebody pull that off? fill an absurd bedroom within our carbon monoxide to kill. detective breitigan knew it's an improbable, but he kept thinking about the logic of the other detective. chirac homes. >> it was a matter of just eliminating the impossible things. at the end, you're stuck with the improbable. >> there is another clue breitigan an allen county prosecutor couldn't ignore. doctor mark when we had a specialty. >> he's an expert in gases, he's an anesthesiologist. >> that's right, an anesthesiologist. a doctor who knows exactly how to put people to sleep. did he use his expertise to kill his wife?
2:25 am
in april of 2007, seven months after kathy's death, detective breitigan got a search warrant for the when you are home. he had a videotape running, his officer sees the computer, papers, and mark's journals. detective breitigan says the journals really caught his attention. >> you have to read the whole thing. i cannot explain that, i wish i could. he was at the end of his rope. i think he felt trapped. >> but, now, all these months later, marco anglers life was on the upswing. he had reconnecting with an old friend, who shared his fate, esther van dine. a romance blossomed. you ended up getting married, i think about a year after kathy's death? >> 14 months, correct. >> some people might think that's pretty fast to bounce back. >> we've heard that. >> the wedding bells had barely stopped ringing, when detective breitigan got a second search
2:26 am
warrant. by now, he had come to believe that mark weiner was a killer. breitigan thought that when we use the engine of some sort, a portable generator, or maybe the vehicles, to put carbon monoxide into the heating system of his home. killing his wife. the detective wanted somebody to take a closer look inside the heating ducts, from the wing or home. >> we went in, and dismantled the duct work. we took carpet samples, and the registers out of the house. >> investigators found a lab -- from an internal combustion engine could be fined inside the heating ducts. it would be months before they got results. do you have any idea that, as you were living this -- investigators were still trying to put a case together? >> we really didn't hear anything for a long time. >> we don't hear anything. >> so you plan a trip to zambia, why did you end up? they're >> one of the churches
2:27 am
in town, a good friend of mine, had gone to zambia with several people from his church. >> they learned that people and zambia were in dire need of freshwater, so march and esther join a church machine to dig wells there. >> after three weeks, it was time to go home. >> you land in atlanta, and your son calls -- >> he says, do you know some guy named breitigan, he's banging on the door. that's >> a detective? >> yeah. >> so you knew then? >> so we knew then. and the atlanta airport that there must have been an indictment, and they were at the door to rest mark. >> the lab results were in, on that duct work. >> coming up, the prosecution's case, motive. >> we have some theories that are pretty dark, that kind of lay out with the state of the marriage was. >> and means. >> can you tell the jury of anything you notice in that bedroom? >> i observe such like marking
2:28 am
on the walls above the register, the here just are. >> when dateline continues. when dateline continues when dateline continues long walks.... that's how you du more, with dupixent, which helps prevent asthma attacks. dupixent is not for sudden breathing problems. it's an add-on-treatment for specific types of moderate-to-severe asthma that can improve lung function for better breathing in as little as two weeks. and can reduce, or even eliminate, oral steroids. and here's something important. dupixent can cause serious allergic reactions, so i think the u.s. was right to threaten extreme sanctions, but it simply wasn't a feasible option to threaten actual military intervention.

here's what's happening, a three judge panel as designed -- to stay in australia. he's unvaccinated, that means he will not be able to play in this year's australian open, which starts tomorrow. djokovic says, he is extremely disappointed with the decision. also, a nearly 12-hour hostage standoff, in a synagogue in eastern texas has ended. >> americans are making more officials say all the money than they were a year hostages are safe, ago. but the suspect is that's the good news. dead. he had the bad news, when the demanded the release numbers are adjusted for of a convict inflation, workers are known as, lady al-qaeda. actually making less, now, back to more than two percent less, on average. dateline the reason is simple. . wages went up, but the cost of living went up more. i want to bring in stacey vanek smith for a deeper dive into this. >> died of carbon stacey is
2:32 am
cohost of npr's monoxide poisoning, daily economics podcast, the indicator, she's also a correspondent for planet money. stacy, good to have you on the show. you've been reporting on something economists call "the money illusion". tell us more about what you found. >> thank you so much for having me. the money illusion basically is that, the illusion of having more money. your paycheck gets bigger, there's a larger number in your bank account, but that money is buying less. so it's the illusion of having more money, but that money isn't buying as much as it used to, mainly because it's not keeping up with inflation. >> so tell us how that translates to real life finance for people who may be making more money than they were a couple of years ago, or for people who really haven't seen a rise in their paychecks. >> well, we know that the average hourly wage in the u. s. is up roughly five percent, a little less. that's s pretty substantial raise for across the country.
2:33 am
this is across industries. inflation, though, is up about seven percent, so that's higher. what that means is that although our paychecks are going up, on average, across the u.s., we are able to buy less with that money. and so it can create kind of an illusion situation because your paycheck looks bigger but a illusion situation because so, -- the defendant was deeply
2:34 am
obsessed with religion, and a divorce would cause him to lose his standing and reputation in the church. if mark and kathy were stuck with each other, and fighting all the time, his journals painted even bleaker picture. >> the man who wrote them, wasn't just unhappy, he was depressed. according to prosecutors, desperate enough to kill. detective breitigan took the jury through each painful entry. >> i am tired of her lies and hiding a huge amount of money from me. she turns away each time i kiss her, she continues to reject my love. i truly want to serve jesus, but i became weak from the wounds that stayed in throws at me, from within my own family. >> just too much before she died, mark wrote this, >> sauces strong again. satan is attacking in a new way this time. using car exhaust. >> that's a right.
2:35 am
flag tells you the state of somebody's marriage, a least in our assessment, that if your marriage is so bad, that you want to kill yourself, whatever things are you willing to do. >> that mention of car exhaust really got their attention. one depressing injury after another, mounting evidence of a man in missouri. in the eyes of prosecutors, a motive. >> 9-1-1 -- >> that 9-1-1 call wray's even more suspicion, as far as prosecution was concerned. >> it just didn't sound like he was doing cpr, on the 9-1-1 call. it sounded like the whole thing was staged. >> if doctor mark wrangler was doing cpr, why would the fire chief fine kathy on air mattress? >> for adequate impressions, it should be on a hard surface. >> is that pretty basic cpr stuff? >> yes, that's basic cpr. >> but, something even more
2:36 am
important cross the chief's mind, after he found kathy. this was a huge red flag for prosecutors. he said, kathy's body was cold to the touch. odd, since mark told 9-1-1 that her heart stopped beating, only minutes before. >> we discuss with each other, in the ambulance, on the way to the hospital, that she was cold. >> which would've been unusual for somebody who had just, minutes before, been breathing with a heartbeat? >> that's correct. >> the er doctor backed him up on that. >> she had a temperature that was quite low. my documentation is that it was 94. >> the doctor also testified that the body seem to be getting stiff. >> it seem like she had been dead for a while. >> in other words, dead before her husband called 9-1-1. >> there was more. the prosecution suggested that marco english grief was phony. >> what was his emotional state?
2:37 am
>> he was acting like he was crying, but i didn't see normal stuff when you cry. >> in the days that followed kathy's death, investigators tested and retested the water heater and other appliances. prosecutors reminded the jury, there was no sign that any appliance had accidentally released carbon monoxide. that was the crux of the case. >> it either had to be the hot water heater, or was murder. that's the bottom line. >> if it was murder, how would you done it? prosecutors believe that mark wrangler closed all the heating vents, except for the one in kathy's room. then, he must of shut the doors to the phone's room, except for the one leading the garage. he could've started a car, or a generator, or maybe both, filling both with carbon monoxide. the carbon monoxide within find the only open path, down the stairs, into the furness. the deadly gas within travel through the heating ducts and
2:38 am
out events in kathy's room. they pointed to pictures taken of kathy's room after she died. >> can you tell the jury of anything you notice in the bedroom? >> i observed a suit like marking on the wall, directly above the register. >> nobody actually tested that stain on the wall before it was painted over, but prosecutors were prepared to show that engine exhaust had come through the heating ducts, and out events. prosecutors now presented the key scientific evidence, designed to wipe out any remaining doubt about the source of the carbon monoxide. live cam in his head tested the -- and said that they indeed found soot that shouldn't have been there. >> that the exhaust from a combustion source was directly -- yes. can you say to a reasonable degree of certainty, that the
2:39 am
water heater was not the source of the sort, in the ventilation system? >> yes. >> devastating for markwayne whose case, maybe. maybe not. >> did a faulty water heater cause kathy wang's death? or was the prosecution's case all just hot air? >> coming, up -- >> ladies and gentlemen, you were here from our -- as applied to the facts of this case. you will find that there is reasonable doubt, but you might even find that the water heaters -- regardless, you will not find that doctor wang glimmered's wife, because he did not. >> when dateline continues. when with rybelsus®. the majority of people taking rybelsus® lowered their blood sugar and reached an a1c of less than 7. rybelsus® isn't for people with type 1 diabetes.
