A Savannah man faces 40 years in prison after a jury found him guilty of computer pornography and criminal attempt to commit a felony.

David Lance Riddle was sentenced to 40 years in prison after his conviction June 23 in Effingham County Superior Court. Riddle was given 30 years on one count of criminal attempt to commit a felony and 10 years to serve consecutively for a second count of criminal attempt to commit a felony.

He was sentenced to 20 years to serve concurrently each on two counts of computer pornography.

Riddle was charged with trying to solicit online who he thought was a 15 year-old girl for a sexual encounter. Instead, he was communicating with an undercover officer. Riddle used a KIK message to arrange a meeting with the girl in August 2015. He was indicted in December 2015.

Prosecutors sought to include two previous convictions. Riddle was sentenced to 10 years of probation for trying to solicit two underage girls for sex after they got off their school bus in Cobb County. His plea deal led to dismissal of two charges of child molestation.

He later was sentenced to three years’ probation for failing to register as a sex offender in 2004 when he moved to Douglas County.
