at that point, i was banging my head against the wall. reporter: linda was also growing frustrated. she was now a widow, a single mom, shunned by her husband s family and eagerly waiting for a break in the case. reporter: a lot of time passed without an arrest. torturous. reporter: every day are you wondering, is today the day or is it never going to happen ? you would kind of get through a point where you d say, okay, we re going to live our lives and when it happens, it happens, you know? and then they d need something from me. and i d get pulled back in again. reporter: one of those times police met with linda to explain there was a problem with the original autopsy. turns out it was incomplete because back then, no one suspected poisoning. many samples like the contents of tom s stomach that might have proved midazolam as the actual cause of death weren t saved for testing. so the d-a s office decided to do something radical.
reporter: the mystery s-u-v left around 5:30am. but tom s car never moved. what does that tell you? there had to be contact between the two to meet at this point, at that hour. so we knew now that someone had met with him prior to his death. and we now have to figure out who that is. reporter: easier said than done, of course. we just pulled up here. and lo and behold, there was a white suv here beside us. there is a white suv there. there is a white suv there. once you think about it, there s a lot of white suvs. they re everywhere. they re everywhere. reporter: but thanks to the video, investigators now thought they had an important lead to help narrow their search. whoever tom was interacting with in this white suv, he was expecting him. and he he knew him. reporter: time for investigators to start looking at tom s inner circle. picking apart his simple suburban life.
remember the anonymous texts to tom telling him about the affair? they came from gill, they found out and he confronted him. i screamed at him. who the hell do you think you are. why would you do this. gill cried and said he did it because he felt tom should know the truth. she said he threatened for forgiveness. tom felt bad that he felt suicidal. tom was that kind of guy. you know, i know this is really a crazy situation we re in but i m not going to let him kill himself over it. we ll work this out somehow. you know. linda says she was still worried that gill was so sidal. that s why she decided to post poen tell her that the affair was over until after the holidays. investigators had to wonder
obviously someone else was there with him that morning. the plot really thickened, i m sure, after seeing that video. yes. so this is the planet fitness right here? this is planet fitness to your right. this is where where tom worked out every morning. i ll pull into tom s spot. reporter: bill weishaupt is a retired f-b-i agent and the chief investigator for the ulster county district attorney. he showed us in the light of day what s hard to see in that grainy video. this is exactly where tom was parked, right here. which is as you can see, it s a great distance away from the planet fitness where he normally worked out. and so this would not be a normal parking spot to pull into at that hour in the morning to work out in that gym. and the mystery suv pulled up where? mystery suv pulled up right here. so they were both facing which is this is north. could you identify a person, a make, a model of the car? what details were you getting? no, it was pitch
kiss on the forehead. reporter: after working out, like clockwork, he always went straight to his job as a physical therapy supervisor. he and linda usually texted soon after. but when linda sent him a message that morning i didn t get a response. and normally, tom s very good at responding. i was gettin a little concerned. but, you know, maybe he s in a meeting, maybe he s, you know, whatever, he s tied up. reporter: she wasn t really worried until her phone rang. it was a friend of tom s named gil. i got a phone call from gil saying have you heard from tom? and i said, no. have you heard from tom? and he said, no, but he didn t show up at work. reporter: what s going through your mind? is there concern or just, oh, maybe he s at the gym? tom would never miss a morning of work. reporter: linda jumped in her car to to retrace her husband s steps, hoping to find him. she never imagined that search would lead where it did. when we come back, linda s
