SAN DIEGO (AP) — A Southern California Marine accused of having sex with a missing 14-year-old girl found in his Camp Pendleton barracks room last summer no longer faces sex crimes charges, military officials said this week.

Under an agreement offered by his defense attorney, Pfc. Avery Rosario pleaded guilty Tuesday to breach of restriction, for leaving the base without permission, the San Diego Union-Tribune reported.

He was sentenced to time served and agreed to be administratively separated, essentially fired from the Marine Corps without a dishonorable discharge.

Before the plea deal, Rosario faced charges alleging sexual assault after he was arrested June 28 when the missing girl was discovered in his room. His attorney maintained Rosario thought the girl was an adult. She was returned to her family.

The decision to dismiss allegations that Rosario sexually assaulted a minor came after consultation with the girl and her family through the girl’s attorney, a military spokesperson told the Union-Tribune.
