A Florida couple left a baby alone in a bathtub to have sex, according to Jacksonville police.

They’ve now been arrested on a charge of aggravated manslaughter in 1-year-old baby Lonzie Barton’s drowning death.

32-year-old Ruben Ebron pleaded guilty to aggravated manslaughter while 26-year-old Lonna Lauramore Barton pleaded guilty to child neglect. Ebron was sentenced to 20 years in prison, and Barton faces up to 5 years in prison.

Ebron admitted to the judge that he left baby unattended in the bathtub of the home he shared with Barton, the infant’s mother.

The two had sex in the bedroom, and when he returned to the bathroom, he said little Lonzie was lying face-down in the bathtub.

He then dumped the child’s body before telling police that it had been kidnapped while he drove to work.
