good evening. tonight, a jury is deliberating a bizarre case involving three doctors, two relationships and one love triangle. the man in the middle now convinced one of his girlfriends spiked his coffee with a sweet poison. she denies it, he's alive. and now he's testifying against her. here's abc's ryan owens for our series, "crime and punishment." >> out. >> reporter: she's a world renowned breast cancer researcher. she was profiled in this video for the susan g. koman foundation. >> one of my aunts died with lung cancer when she was 35, i was 10, so, that was when i made the decision this is what i wanted to do. >> reporter: but did anna gonzalez, who dedicated her life to healing people, also poison one? >> the defendant had a fatal attraction. >> reporter: tonight, a texas jury is deliberating that very

question. >> and the evidence is going to show you that she became absolutely and totally obsessed. >> reporter: and we'll get to all that, but first, the basics. prosecutors say in january of 2013, the 43-year-old colombian-born oncologist spiked her lover's coffee with a chemical found in antifreeze. >> you can't tell it's there by looking. >> reporter: it's also common in laboratories, including those at houston's md anderson cancer center, where dr. gonzalez and her lover both worked. a highly regarded lu eed lung c specialist testified that the two lovers engaged in oral sex, shared a vodka shot and headed into work. before they left gonzalez's house that morning. >> she had a special coffee she wanted me to try. >> reporter: he knew immediately

something was wrong. >> i said, what's up with the coffee? >> reporter: this will kill you, but the taste is sickeningly sweet. >> what did she say? >> she said, oh, i put splenda in it. >> reporter: the jury watched this cell phone video, shot hours after he took a few sips of that coffee. dr. bloomen shine is in the hospital waiting room and has a tough time even forming sentences. >> i've gotten progressively, um -- discoordinated. >> next to him, dr. anna gonzalez, who would later be charged with aggravated assault, to which she pleaded not guilty. behind the camera, dr. bloomen shine's long-time girlfriend, avett tony. >> i actually thought, he's dying in front of me. >> reporter: at the time, she had no idea her man was having an affair with his fellow researcher, dr. gonzalez. but she knows now. >> i felt stupid. i was there for three weeks and i kept thinking to myself, you

made me look like a complete idiot, nobody said anything to me about this. >> reporter: by the next day, dr. bloomen shine's kid nighs failed. he was close to death. >> it's just hard reliving this. because i almost died. >> reporter: after weeks in the hospital, he pulled through, and began his own quest to find out who poisoned him. >> blood and urine taken at the hospital found no traces of the poison in bloomen shine's body. i think the state is proceeding under the theory that this is a mystery like a puzzle. why did he go in to kidney failure within a certain period of hours after he drank the con co concoction in those are the pieces of the puzzle. >> reporter: he suspected dr. gonzalez. he even secretly taped phone calls trying to get her to admit to it. >> i'm not a crazy person a, we were friends, but after all what happened, you need to understand that i feel pretty bad.

i feel pretty used and i feel completely betrayed. >> reporter: in the tapes, drchl gonzalez repeatedly points the finger at the other woman. >> why in christ would ill ever hurt you? why? >> why would evette hurt me? >> i don't know. i don't know you two. i would have run away a long time, but you know, i mean, it's different. you seem to know things better. you seem to know her better. you trust her. >> reporter: there were five more hours of them and the judge did not allow the jury to hear the most explosive parts. like when the colombian-born doctor brags she'd had people assassinated and that she takes care of things the clolombian way. backing aside, what could push a woman to allegedly poison a man who just minutes before, she was intimate with? >> dr. gonzalez, if this is true, wanted to exact a revenge. she was hurt. but we have to look at the fact that people have hurt every day.

i certainly would say that the dividing line is someone who may have more of a pathological behavior. >> this is a friendship because i trusted you. >> reporter: we should point out dr. gonzalez was not charged with a crime in colombia or anywhere else, except for the poisoning of her lover here. and her defense team says the state's case is just a guess. that there's not a shred of evidence. their client poisoned anybody. >> what we are engaged in and what they are going to be offering you is little more than guesswork. and folks, we don't guess people into felony convictions. >> reporter: today, they shocked the crume kroum by handing thei client's fate to the jury as soon as prosecutors rested their case. >> ladies and gentlemen of the jury, the defense also rests. >> the defense in this case, i think, made a brilliant move, by not putting up witnesses, they suggest the state's case is so weak, they didn't need to put up witnesses. >> reporter: while prosecutors

admit their case is kish circumstantial, they believe she poisoned him because he chose the girlfriend over her. a twisted love triangle that left one man almost dead and another woman still standing by him. >> are you still with george bloomen shine? >> yes. >> i'll ask what everyone in the room wants to know. why? >> because i know the affair with the defendant is not the sum of who he really is. >> reporter: will the third member of that love triangle spend the rest of her life in prison or could she walk away a free woman? tonight, only a jury of seven women and five men will determine that. i'm ryan owens for "nightline" in houston. next, it may seem like you're getting a great deal with the je merrick version of your meds, but are you really getting what you think? and later on "nightline," we're on tour with ed sheeran.

generic medications save us more than $200 billion a year. a bargain for the same product with just a different name, right? well, "nightline" investigated and it turns out, some of those drugs are far from identical to the brand new ones. and that could mean you aren't getting what you think. here's abc's senior national correspondent jim avila. >> reporter: when robin lynn was prescribed a generic version of a popular drug, she didn't think it was going to be a big deal. >> i thought all along that generic drugs are the exact same

thing as the name brand drug. >> reporter: well, why wouldn't she? 8 out of 10 prescriptions written in america today for filled with the no brand new version of the drug your doctor prescribed. it's the exact same formula, right? >> by the middle of the day, i would sort of have no energy and crash. >> reporter: maybe not. >> i knew that that was just not normal. >> initially, we heard from just a couple of dozen and then eventually hundreds. >> reporter: and it wasn't just her drug. harry lever, a cardiologist from the cleveland clinic, found what he says was a similar problem with a generic form of blood pressure medication. >> patient would come in to see me and i started to notice that they weren't doing as well as that they were on the name brand drug. >> this is the people's pharmacy. >> reporter: this story really begins with consumer watchdogs joe and terry grade. strong advocates for the use of generic drugs. >> next time on the people's pharmacy, we'll bring you up to

date on the health stories behind the headlines. you can save an amazing amount of money. what's not to like? >> reporter: soon, they found plenty not to like. >> coming up -- >> reporter: right around the time robin reached out for answers, joe said he began receiving a rash of complaints about the same drug robin was taking, a generic form of wellbutrin. >> you they were getting very jittery, experiencing headaches and some of them even expressed suicidal thoughts. >> it was like getting a shot of adrenaline first thing in the morning. it would make my hands shake, my heart would pound. and it wasn't really controlling my depression symptoms. >> reporter: worried about robin and hundreds like her, he contacted the u.s. food and drug administration. >> hey, something strange is going on here. could you investigate? and pretty much we heard nothing back. the fda didn't seem very

responsive to our concerns. >> reporter: so, he decided to investigate on his own. while generics have to contain the same active ingredient, the medicine, the fda does allow them to use different inactive ingredients. binders to hold the pill together and time release agents to disperse it. he enlisted dr. todd cooperman. he runs consumerlab.com. independently testing generic drugs and how quickly they release their active ingredients. >> what we found was shocking. the generic released its ingredient very quickly. so, you're getting a burst of medication coming out very early on with the generic that you shouldn't be getting. >> reporter: leaving little drug for the rest of the day. >> it seemed like the fda wanted to kind of quash this issue. >> reporter: the package insert that came with the drug stated that the drug had been tested in a study. and e give lance was demonstrated with the name brand, wellbutrin. but then, a shocking admission from the fda. >> the fda finally admitted that

there had never been a study on this generic, never been tested in humans and that the information in that package insert was thejust made up. >> reporter: we went to see j someone at the fda to get an explanation. >> there was concern about testing the generics in normalñ volunteers. we had had seizures reported and we were worried that we would be unethically exposing volunteers. >> they didn't want to do that test in healthy people, which seems ridiculous. i think they made a big mistake there. >> reporter: the fda did require testing in a lower dose of the drug and used those results to approve the 300 milliongram strength. finally, five years after the first complaint, the fda took that strength off the market in 2 2012. >> in fact, it was not

equivalent enough to the brand drug. >> reporter: and so that's the reason why it was recalled? >> that's correct. >> tune in for the health news that matters. >> we felt vibd kated. after being told for so many years that we were totally wrong, that it was all in people's minds. >> reporter: people do wonder when they are prescribed a generic drug, is this just as good, is it the same? what do you tell them? >> yes. we stand behind the fact that generic drugs that are in the u.s. market have -- deliver the same performance as the brand drugs. >> reporter: other forms of generic wellbutrin are still on the market and they are all considered safe, in fact, experts agree that generic drugs are, in general, extremely safe. but remember that heart medication? after dr. lever complained, the fda announced that two generic forms of that drug manufactured in india were voluntarily recalled, even though the fda said it was up to standards. is that just a coincidence? >> we think it is a coincidence.

we have tested all the products on the u.s. market, all right? and we find that they're all adequate. >> reporter: she says these recalls were routine and due to some specific lots that may have degraded over time. dr. ready is one of the company's that manufactured the drug, also told abc news that the voluntary recall was related to specific manufacturing issues with the two batches in question and not related to manufacturing of any other batches. dr. lever isn't buying it. >> all i can speak to is what i've seen. and i've seen problems. and when you have batches that are removed, you begin to wonder that there are problems and you can't just ignore it. >> reporter: the watchdocks like joe and dr. kooperman believe most generics are completely safe. they still have concerned. >> we suspect there are at least dozens, if not scores of generic dregs that may not live up to the standards that the american publix expects.

>> reporter: the fda disagrees. for "nightline," i'm jim avila in washington. next, don't do it. ed sheeran reveals the upside of having someone steal your girl. we're on tour with the unlikely teen pop sensation who now has 0 no shortage of fe ♪ ♪ fill their bowl with the meaty tastes they're looking for, with friskies grillers. tender meaty pieces and crunchy bites. in delicious chicken, beef, turkey, and garden veggie flavors. friskies grillers. that's all i crave.e that's where this comes in. only nicorette gum has patented dual-coated technology

the bro code? >> yeah. it's a difficult conversation to have. he was my mate. so it was just a little bit, ah, not cool. >> reporter: do you regret writing about such personal things? >> i think it's nice to get something positive out of a bad situation. the song will live on forever and people will be able to find solace in it. >> reporter: sheeran's moved on in style, performing at the grammys with fellow brit and role model elton john. i understand that taylor has given you advice on how to have longevity in a career as opposed to just being a flash in the pan. >> constant humility, constant evolution. >> reporter: for "nightline," i'm juju chang in mansfield, massachusetts. >> and entertain, he does. thanks, juju. finally tonight, late-breaking
