Sharon Rocha was sitting on the couch next to her pregnant daughter, Laci Peterson, when the 27-year-old said the baby was kicking. "I put my hand on her stomach, because I’d never felt him kick," Rocha says in a new ABC documentary about her daughter's murder, per People. "She leaned over to me and she said, 'Mom,' she said 'Scott doesn’t like to do this.' She said, 'I’ve asked him about, you know, feel my stomach when the baby kicks, and he never wants to touch my stomach.' That really, really bothered me. And that was the last time I saw her." Peterson, eight months pregnant, disappeared soon after on Christmas Eve in 2002; her body and that of the son she was carrying washed ashore in California four months later and her husband, Scott, was eventually convicted of her murder; he is still fighting his guilty verdict and death sentence.
In the documentary, which debuts Sept. 14, Rocha says the realization that Scott may have had something to do with her daughter's disappearance was a difficult one to accept. "It’s not like this is a total stranger that you might be suspecting," she says. "This is somebody that’s been a member of your family for several years now, and it’s really, you know, the back and forth and the guilt about feeling this way, and how it may have an effect on the relationship with my daughter if I’m wrong." She adds that Scott had been a member of the family she "loved and cared about," and that knowing how Laci felt about him made her not want to consider him a suspect. A&E is also currently airing a series on Laci Peterson's murder; People reported last week that in that series Scott Peterson was recently heard describing the "terrible physical reaction" he claimed to have upon finding out his wife and son were dead.
