tells me, "i'm sorry. i never meant for this to happen." and i didn't know -- >> that's kind of -- >> --what that meant. >> --a funny thing to say. what do you think he meant? >> i don't know. >> "i didn't mean for this to happen"? >> i -- i didn't know what he meant. i just -- you know, i was thinking, "he didn't mean to leave her while he was in california." or, "i didn't mean to have that affair." it coulda meant a lotta things. >> reporter: tamara also recalled that early morning phone call she received from david on the day kay was found beaten. >> he was asking me if i had talked to kay. and the thing about it is, he's never called me during the day, so it was just very unusual for him to call me and ask me if i had talked to kay. >> reporter: it seemed strange to tamara then, perhaps even stranger now in light of the new questions about david. people in town whispered and wondered, did david somehow have a hand in kay's murder? a way perhaps to avoid and ugly and expensive divorce? >> she said, "well, if i ever found out that david was havin' an affair on me, i would be gone."
