America was horrified when a booze-soaked pervert was accused of getting a one-year-old girl drunk and killing her – and now The National ENQUIRER has learned of his scary history of sleeping with small kids!

Accused killer Andrew Becker, 33, may have also been motivated by an ugly divorce, The ENQUIRER has found. On March 15, cops say Becker took Liliana into his room because he missed his estranged wife’s daughter. The next day, say cops, his mom Carolyn saw him carry Liliana’s body from the room!

In an exclusive interview, a woman who dated Becker said his desire to sleep with kids was an ongoing, non-sexual fetish. “It was an affection thing, but it wasn’t right,” 
she said.

Initially, Becker insisted he didn’t kill Liliana, but her autopsy showed a blood alcohol level of .04 percent, as well as bruises. He finally admitted “harming the child” and chugging eight shots of vodka before bringing her into his bed, say court papers.

He was arrested in August on charges including third-degree murder, and is on suicide watch.
