wearin , you know, her jacket and a couple of scarves. i i saw what appeared to be a bullet hole in her in her scarf that was wrapped around her neck. and that s when i observed a hole in her neck. reporter: so she was killed presumably by somebody who got into the house and waited for her in the garage? possibly. yeah. or, um she opens the garage door, she pulls in and somebody runs in there, shoots and kills her and takes the car. reporter: all right, so so an alert goes out for the car, right? correct. yes, sir. reporter: there were so many scenarios under consideration. this didn t feel like a burglary or a carjacking. the medical examiner outlined anna s cause of death. he was able to document that she had been shot six times. reporter: they found a seventh bullet in anna s clothing that hadn t penetrated. in fact, it fell onto the examining table. the deadly bullet wounds were close together. someone had shot her in the chest, and then in the back.
from talking to him on the phone a couple hours ago, he seemed all right. all right? yeah. how can he be all right? he can t be all right. reporter: as the ex-husband, investigators, of course, asked about the broken marriage. bob and anna divorced two years before anna was murdered. did y all ever fight whenever y all were married? i mean, we had disagreements. i mean, that s kinda, why we re divorced. i mean, we just we re kinda like, opposites in some ways. gotcha. reporter: the investigators asked bob if he owned guns, and he said yes, five of them. three were .22-caliber, the kind of weapon that killed anna. bob readily agreed to let police search his home and take his guns and ammunition. we re gonna have to get em analyzed. bob even provided a dna swab, right on the spot. this is a q-tip, a big long q-tip. so i want you to go ahead and rub it on your left cheek. left. we use this evidence in to
piece? have you ever heard anybody respond like that? never. reporter: to a death notification. never. reporter: but it wouldn t be the only response that left sgt. reim scratching his head. so i ll let you talk to a detective and and we ll go from there, if you re good with that. i do have class. even though i know that s kind of insignificant at the moment. okay. yeah, i think i think you can get an excuse for that. reporter: igor never made it to class that night. instead, he was brought here to the frisco police department for a formal interview. investigators had already been briefed about his odd reaction to the news of his mother s death. later, he d tell her friends he didn t want to have a funeral for her. and also this that whoever had killed anna moses should be forgiven. igor said he was in class the night his mom was murdered. but after interviewing him for five hours, investigators were still wondering about his unusual reaction. especially when the
that s what it appears to be. that he s, you know, givin her money in maybe hopes that, you know maybe at some point, maybe she would gain some interest in him. reporter: when they burrowed deeper into anna s finances, investigators found about $111,000 in her bank accounts, money cops thought her university job couldn t have provided. and the professor s generosity accounted for less than half of that. so all that money begged a lot of questions. reporter: was somebody else giving her money? i have no idea about that. ah, this is new to me. if she had asked me, i would give her money. if she was in need, i would have given her money. reporter: the unaccounted for cash was just another piece in a puzzle that already featured more characters than a hollywood caper. this is a good whodunit case. we didn t know a lot at that time and we had to rely on the investigation and the crime scene and evidence to point us to who did it.
one of them was reuben mankin of the texas rangers. my initial observation was just from coming in through the foyer was that it was a clean house. then i made a beeline for the the laundry room, which was reporter: wait one sec. clean meaning didn t look like she d interrupted a burglary? that s correct. that s correct. reporter: i mean, there was no stuff missing, drawers pulled open? right. reporter: something else was telling on the floor of the garage was anna s purse, which still held $300. and nothing else seemed to be missing, except anna s car. ranger mankin surveyed the scene with lead detective brian tschudy. that s when we notice some shell casings in the garage. um, just multiple shell casings. reporter: the casings easily identified the murder weapon as a .22 and a careful look at anna s body told them a little more. i observed her to be lyin on her back. she was heavily clothed still
