An arrest warrant was issued early last week for Ruben Ebron, the man sentenced in the death of 21-month-old Lonzie Barton. The new warrant is related to a sexual assault case from 2006, the State Attorney’s Office confirmed to First Coast News Thursday.

Ebron, 33, is accused of sexual assault on a person over the age of 12 in Leon County 10 years ago, according to the warrant.

The warrant, signed July 11, orders a $25,000 bond and that he has no contact with the victim. The bond is moot, as Ebron is in a state prison.

He is serving a 20-year sentence for aggravated manslaughter and child neglect after toddler Lonzie died while in his care almost a year ago – and he stashed the body under a pile of tires in the Bayard area of Jacksonville.

He and the child’s biological mother, Lonna Barton, each entered guilty pleas and were sentenced in the toddler’s death. Barton received five years for her role in Lonzie’s death, and was also sentenced to prison for drug charges in Baker County.
