>> we appreciate your time as always, join us again at 6:00 welcome to "world news." tonight weather whiplash, temperatures suddenly plunge across america, now shivering through what could be one of the coldest world series ever. a beloved teacher tragedy, a 14-year-old boy stands accused of her death. real money, saving $1,000 on cable, internet and phone bills. how your family can save a lot, too. and a royal wave tonight from a future king. and a good evening to you. we begin with the head-spinning shift in the weather tonight. from north dakota to maine, families trading yesterday's shorts for parkas and ear muffs. what a difference 24 hours makes, and in just one stretch

of the country -- milwaukee, detroit, columbus -- temperatures plunged as much as 25 degrees. abc meteorologist ginger zee is here to tell us how much colder we're all going to be. >> reporter: frost, freeze, even snow. hello october. in boston, a big brr to start the world series. temp 47 at first pitch. it will likely be the coldest world series ever for fenway. still a solid ten degrees above the coldest world series game on record though. it was only 38 at first pitch in cleveland, ohio in 1997. this year's chill pouring in and pooling down along that sinking jet stream. across the great lakes and upper midwest, temperatures up to 20 degrees below average. these men in maryland celebrating the first flakes of the season. ski resorts are cheering, too. from snowshoe mountain resort in west virginia to wisconsin, where they're firing up the snow machines. >> prior to this october 31st,

making snow on halloween. >> reporter: in iowa they had their first wet flakes flying. the first and, as we all know, far from the last. >> it's kind of a hint from mother nature that winter is not far away. >> reporter: although overall the climate prediction center has the areas shaded in orange above average for the next three months. the pumpkins here on long island behind me are safe but i can't say the same for so many others. look at this map. tonight we've got freeze watches, advisories or warnings, frost advisories in place for at least 21 states. that's not just from st. louis to atlanta but the northeast, too. it's settling in and we are bundling up for the next couple of nights. diane? >> thank you so much, ginger zee. now we move on to the new tragedy at another american school, this time a high school in massachusetts. 48 hours after a 12-year-old shot a teacher in reno, another beloved teacher found dead, murdered. this time a 14-year-old member

of the soccer team is under arrest. abc's gio benitez with the very latest. >> reporter: behind this smile, a young math teacher, just 24 years old. colleen ritzer was nothing short of beloved. >> she was one of the best teachers danvers high has ever had. she really made an impact in everyone's lives. >> reporter: but overnight, her body was found in the woods, near the massachusetts school she loved so much. and, this afternoon, one of her own students was charged with her murder. police say 14-year-old philip chism stabbed ritzer in a school bathroom, and that surveillance cameras show him moving her body out to the woods. his alleged motive, still a mystery. he's pleaded not guilty. ritzer is the second teacher this week has been senselessly killed at school, allegedly at the hands of a student. monday, 45-year-old

michael landsberry, also a math teacher, was shot to death in sparks, nevada. ms. ritzer's final tweet to her friends was about that tragedy. "my thoughts and prayers are with those involved in the nevada middle school shooting. simply devastating." today, her best friend described her as overflowing with life. >> she didn't need big, crazy things to make her happy. she could find joy in anything. she brought so much joy into my life. >> reporter: on twitter ritzer called herself a "math teacher often too excited about the topics i'm teaching." >> she was born to teach. she always loved working with kids. i think they just gravitated towards her and i think as much as they loved her she loved them 100 times more. >> reporter: chism had recently moved here from tennessee. he was on the soccer team. last night, he missed practice and his teammates went out searching for him. >> what kind of person is he? >> soccer is like one big family. we all knew him. we all liked him. he was nice. we just never saw it coming.

>> reporter: and that 14-year-old's mother was in court today. her son was charged as an adult. tonight the key question that nobody seems to have an answer for is, why was that teacher killed. >> thank you so much, gio. and this note, we talked about the world series. tonight the boston red sox observing a moment of silence for colleen ritzer. now we move next to the white house and an awkward telephone call for the president today. everyone wondering if he got an earful from one of the most powerful leaders in the world, angela merkel of germany asking if the u.s. was listening in on her private cell phone calls. here's abc's global affairs correspondent martha raddatz on the complaints pouring in from america's friends. >> reporter: like almost everyone else in the modern world, chancellor merkel spends a lot of time on her cell phone. and whether it's righting europe's economy or chatting with family, she assumes it's private.

which is why today's accusation is sparking outrage. german officials today saying they have received information that the chancellor's cell phone may be monitored by american intelligence. president obama was in touch with merkel almost immediately. >> i can tell you that the president assured the chancellor that the united states is not monitoring and will not monitor the communications of the chancellor. >> reporter: but listen carefully. he said is not monitoring and will not monitor. that leaves out whether she has been monitored in the past. this follows report of nsa spying in france, mexico and brazil, almost all based on leaks from former nsa contractor, edward snowden. tonight, president obama was supposed to host brazil's president. that was before she cancelled over those accusations the nsa was spying on her. right now these revelations are clearly embarrassing the u.s.

and leaving even our greatest allies a lot less friendly. >> thank you so much, martha. we have another note from washington now. today ceos of the most powerful insurance companies in america, aetna, wellpoint, kaiser permanente and others, gathered at the white house to brain storm a fix for the troubled obama care website. congressional hearings began tomorrow and already one democratic senator, joe manchin of west virginia, has announced he's going to draft a bill to extend the deadline for signing up. now a new study bringing insight into a persistent health problem in the western world. too many of us taking way too many antibiotics every year. it creates resistance, even stronger disease. abc's medical editor, dr. richard besser, tells us the surprise that some of it is happening because of the words we say to our doctors. >> reporter: we want them and we get them. antibiotics we don't need.

today's study followed thousands of patients with colds. if they were hoping or expecting to get antibiotics, they were much more likely to get them. we know that a full 50 percent of the antibiotics prescribed today are not needed. doctors feel patients expect them. >> sometimes i do feel bullied or a little bit pressured into prescribing antibiotics. >> reporter: today's study finds that patients who leave with a prescription are more satisfied. so even saying things like, "what can i take?" or, "i had antibiotics for this before" may just get you that prescription you don't need. a big problem. because each time you take an antibiotic, it becomes a little less effective for you. do this over and over again and you end up with antibiotic resistant infections that are harder and harder to treat. take a little quiz. do you need antibiotics for the common cold? no. colds are caused by viruss.

the flu? again a virus. antibiotics are useless. a sore throat? antibiotics only work if it's strep and that's just ten percent of the time. >> richard is here now. tell me again what we say and do not say to the doctor. >> i see patients who are sick all the time. what they want to know is how they can feel better sooner. ask your doctor, "how do i treat these symptoms?" and if they're not going away what should i look for that might tell me this is something that does need an antibiotic. if you do that you're going to avoid a lot of unnecessary drugs. >> don't go in saying can i have an antibiotic? >> that's the worst question you can ask. now we move on to to a new development from a famous trial in the past. today a judge in connecticut ordered a new trial for michael skakel, a cousin of the kennedy family. you'll remember he was convicted in 2002 for the death of his neighbor, martha moxley. they were both 15 years old when she was killed in 1975. he was sentenced to 20 years to life and served more than a

decade in prison already. the judge said skakel's attorney did not adequately represent him at that first trial. and tonight a lot of american families are on the alert, worried about the family dog or cat. the fda has warned about the mysterious outbreak apparently linked to treats made in china. abc's david kerley tackling the new questions tonight. >> what a good boy you are. >> reporter: mugly is one of the survivors. >> we thought that there was a good chance that he could die. he was very, very sick. >> reporter: he says his terrier mix ate jerky treats like these from china. over the past six years more than 3,600 dogs have been sickened and 580 have died. is there something in the treats sold under various brands? what might it be? it remains a mystery. tonight the food and drug administration has this letter out to u.s. veterinarians, collect more samples from sick dogs suffering kidney failure and intestinal bleeding.

the government is stumped after 1200 separate lab tests and even sending officials all the way to china to inspect the two largest treat makers. symptoms can come on in hours. for dog owners, look for decreased appetite, activity, vomiting and drinking more water. >> we went through hell with this. >> reporter: tonight he considers himself the lucky one because his dog survived. david kerley, abc news, washington. now another note in the news, a big day for a little prince, prince george. his parents, grandparents and great grandparents and seven godparents gathered for his christening, the whole world watching to see if the tiniest royal is ready for his closeup. >> reporter: it was the glimpse the world was waiting for, baby george, third in line to the throne. proud dad teaching him the age-old tradition, a first royal wave, tiny hand lifted high, just like his other relatives

have perfected over the years. after all, one day he will be the king of england. so well behaved on his big day william telling the queen, quote, perfect timing. he's just gone quiet. he's already so far so good. the royal christening steeped in tradition. in fact, since 1841 60 royal babies have worn the same satin gown, from the queen herself to prince charles and prince william. but in 2004 the queen felt it was too fragile so she commissioned her dresser to make an exact replica for future generations. as for george's godparents, william and kate choosing seven in total, college and school buddies, a royal cousin and one of william's mother diana's friends, his way of involving his mother in their lives. a day of love, family and tradition wrapped up in one tiny bundle of joy. lama hasan, abc news, london.
