The Florida Times-Union reports 26-year-old Lonna Lauramore Barton was sentenced Friday after she pleaded guilty to child neglect and lying to police.

Lonzie Barton was reported missing last summer and after months of fruitless searching, Barton’s ex-boyfriend 32-year-old William Ruben Ebron Jr., led investigators to her remains in January. He pleaded guilty to aggravated manslaughter and is expected to be sentenced to 20 years in prison.
