An inmate at the center of recent leads in the disappearance of baby Sabrina Aisenberg has agreed to plead guilty to an unrelated federal weapons charge, according to court documents filed Friday.
Scott Overbeck, 44, faces a maximum of 10 years in prison on a charge of being a felon in possession of a firearm or a destructive device. He is scheduled to enter his guilty plea before a federal judge Wednesday.
Overbeck's name became intertwined with the Aisenberg story this summer, when the St. Petersburg Times learned convicted felon Dennis Byron, 33, a longtime friend of Overbeck's, told detectives that Overbeck had admitted to disposing of the baby's remains.
Sabrina was 5-months-old when she went missing in 1997 from her Valrico home. A federal case accusing parents Steve and Marlene Aisenberg of lying about their daughter fell apart in 2001. A judge threw out the charges against them.
No one has been arrested and no new charges have been filed.
In a jailhouse interview earlier this year, Byron told the Times that information he provided detectives won him freedom from a three-year prison sentence. But he violated house arrest, and the sentence has been replaced by a five-year one.
Byron said detectives had him secretly record conversations with Overbeck when they shared a cell and that Overbeck admitted to cutting up the baby's body and disposing of it in Old Tampa Bay.
Overbeck's federal case began after Hillsborough Sheriff's detectives executed a search warrant in December at his Tampa home at 9303 E Eden Roc Circle. Investigators had probable cause to believe that Overbeck was in possession of and distributing narcotics from the home, according to court records.
While inside, authorities recovered a "possible destructive device," court records say, which was later found to contain explosive powders, a fuse and 12-gauge shotgun shells that would act as fragmentation.
