>> my husband! >> it made my blood boil. i was shaking, i think, literally, when i heard this stuff. >> reporter: bob's family said the defense case for no resemblance to reality. prosecutors agreed. >> is there any credible evidence at all that chacey was poynter abused by her husband? >> no. >> there is no er visit? >> no 9-1-1 calls. >> no previous law enforcement at that address? >> no one else saw robert poynter even get mad. he's been described is a big teddy bear. >> reporter: on the other hand, they did find plenty of evidence that chacey wanted bob gone. >> she's fishing around for multiple men to commit this murder for her. >> reporter: that's right. it turned out key michael garza wasn't chacey's only lover. in the month up to the murder, she had been juggling three other boyfriends. detective burke brought them in for questioning. >> a lot of it was for sex. >> reporter: along with frequent meet up for sex, two of her lovers told police, chacey also shared the story of abuse that she claimed with suffered at the hands of robert poynter. >> she did tell me that he heard her a lot and that there was a lot of abuse going on. but he would never leave marks because he didn't want no trace. >> she would meet these guys, they'd be interested. and she would immediately start telling her story, right? my husband is beating me, i'm in this terrible marriage, i feel threatened. but ... maybe there's something here with you and me? >> exactly, that's her mo. she plays the victim and manipulates. >> reporter: among chacey's stable of men were a couple of firefighters. they were not, however, from her husband fire company. that was apparently where chacey drew the line. to one of those firefighters, a guy named danny, she texted this about her husband. i wish he'd run out of aaron afire. to another, named sean, she texted, i only have one way out of this and it's not going to happen anytime soon. minutes later, he texted. yeah, not an option. and then this exchange. i hate him so much, chase he texted sean. his response? shoot him. in she replied, i don't look good in orange. >> she's looking for someone besides the three that she had been involved with, and michael garza comes along. >> she wanted someone to do her dirty work? >> absolutely. >> the same day, bob was traveling home from that vacation in mexico, she texted garza. me more than anyone wants him. gone garza's reply? well, it can happen. before their trip to mexico, bob had already suspected that chacey was unfaithful. >> and you say, chase he is losing a lot of weight. but she's not doing it for me. >> really? that's not a good sign. it was when they return from the trip that bob started taking trips steps to end their marriage. he contacted his attorney via facebook. not divorce hopefully? it's looking like it. i have tried and tried but i think i want to file first and keep custody. do you think she seeing someone else? i kind of do you think so but a lot of lies lately and i'm tired of it. prosecutor said, divorce was the last thing that chacey wanted because the couple had a prenuptial agreement. bob had insisted on it. and so chacey believed she wouldn't get a dime if they split. >> over six figure income from university park as a way fire captain. in addition, he works a lot of side jobs. there is no way he would be able to support herself. >> so that? works >> that works. >> on the other hand, if obstinately died, chacey would be flush with cash. months before the murder, she convinced bob to make her the beneficiary of his life insurance policy. >> $680,000 in a lump sum. okay? >> you think robert essentially signed his death certificate the day he changed his insurance beneficiary? >> absolutely. >> reporter: prosecutors believe that win chacey found out that bob had made contact with his attorney, she had to move quickly. >> she had been planning to kill him. >> so the divorce was to push her foot on the accelerator? >> absolutely. >> reporter: prosecutors said that the murder was chacey's and not garza's, and all about the money. that's why, just before trial, they raised the charge against her again to capital murder. now the jury had to decide, if they found she killed bob for money, the sentence would be a life without parole. but if they believe any of chases varied stories, they could set her free. when the verdict is announced, are you looking at her? >> yeah, we all were. >> what did she do? >> she was standing there, looking down, the firemen were all there. we all just clinched our hands like this. the >> reporter: verdict? guilty of murder. but crucially, the jury did not find that chacey did it for the money, which could mean a lighter sentence. >> my heart dropped. >> mine too. >> i felt. sick >> i thought it was very, very clear that she did it for money. and i was putrefy that he was going to get, like, ten years. >> reporter: the jury didn't do that. they sentenced chacey to life in prison with the possibility of parole. she'll be 59 before she can be released. >> she has to live with what she did. i don't know. >> you have to live with it too. >> it took me a long time to get over bobby's phone calls that weren't coming through anymore. >> reporter: her phone still rings but now it's the firefighters who worked with her son. >> he always told me, mom, if anyone anything ever happens to me, you will have a second family. >> i said, really bobby? he said, you have no idea. >> he was right. >> truly. >> that's all for this edition of "dateline" i'm, natalie morales. thank you for watching. >> i'm craig melvin. >> and i'm natalie morales. >> and this is "dateline.
