david: j. everett tuttle. the billionaire? yeah, he's a hedge fund manager, he's into philanthropy and politics. three of the people on rachel's list worked for one of his companies. that's not much. i mean, a financial wiz hiring statisticians. "not much" is all we have. i finished the forensic autopsy on rachel lawton. it was smart to request a second one. why? what do you got? apparently, her killer didn't have a lot of patience. although she had a potentially lethal dose of alcohol and painkillers in her, rachel lawton died of asphyxiation. how? she had traces of cotton fiber in her lungs, likely suffocated from a pillow or towel after she was unconscious. sort of thing that, in the absence of suspicious circumstances, might be missed. so we're not talking about five random deaths, we've definitely have one murder on our hands. we're gonna need forensic autopsies on the other victims. i'll get it started. we might be looking at five murders. yeah. but we have no idea what they're about. survives 10x better to get where you
