A Cobb County man was sentenced to 50 years, including 30 in prison, for enticing and molesting a girl he met on Facebook, the county’s District Attorney said Friday.

Jorge Renberto Ventura, 28, of Marietta, was convicted Thursday afternoon of two counts of child molestation and one count of enticing a child for indecent purposes, DA Vic Reynolds’ office said.

The girl testified that she met Ventura through Facebook, and that about 6 p.m. on Aug. 5, he came to her house and forced her into her bedroom, where he touched her inappropriately, Reynolds said. The girl was 13 at the time.

Ventura ran out the back door when the girl’s father got home, according to prosecutors. Ventura was arrested Aug. 14 and has been held in the Cobb jail since then, booking records show.

“This defendant gained the trust of this young girl, then used that trust to gain access to her home, and ultimately, her body,” Assistant District Attorney Susan Treadaway said. “There are no more despicable acts than these.”

At his sentencing hearing Friday morning, Ventura asked for mercy and said he was innocent, Reynolds’ office said.

A felon, Ventura served in state prison from May 2011 until April 2012 following a conviction in Cobb County for terroristic threats, according to the Georgia Department of Corrections.

When released from prison after his current sentence, Ventura will be required to register as a sex offender.
