ONSLOW COUNTY -

A man will spend more than two decades in prison after admitting to the murder of his 19-year-old girlfriend.

Timothy Akers, of Jacksonville, pleaded guilty to second-degree murder in Onslow Superior Court Monday in the death of 19-year-old Caitlyn Culpepper. He was sentenced to 20 years and five months in prison.

Police said they found Culpepper's body in July 2011 on the 100 block of Hardison Hills Court in Jacksonville. The victim had a gunshot wound.

According to Culpepper's parents, the victim had been dating Akers for about seven months.

Culpepper was a gospel singer who was born in Morehead City. She grew up singing at Reece's Chapel and toured other churches across North Carolina.

Akers' father was the deputy provost marshal at Camp Lejeune when the crime happened.
