A Russell man has pleaded guilty to charges stemming from his attempts to contact underage girls.

Adam M. Larson, 40, entered the plea last week in county court.

He pleaded guilty to charges including two counts of unlawful contact with a minor at one docket and criminal attempt (unlawful contact with a minor) at a second docket.

The plea brings a 25-year registration period as a sexual offender, according to information from the Warren County District Attorney’s Office.

“The District Attorney’s Office was made aware of an individual ‘fishing’ social media accounts and texting individuals throughout the area attempting to locate and meet underage girls,” Chief County Detective Tom Kibbey said when Lasrson was charged back in January.

Investigators identified the man as Larson.

“Warren County Detectives acting covertly received obscene and sexual messages and images from Larson,” First Assistant District Cody Brown explained in December, “who was subsequently arrested when he arrived at a predetermined location to meet who he believed to be a 14-year-old female.”

According to the Pennsylvania State Police sexual offender registry, Larson was convicted in 2010 on charges of sexual abuse of children, unlawful contact with a minor and two custody interference offenses that occurred in 2009.

He’s deemed a sexually violent predator, which means his registration is for his lifetime.

County detectives were assisted by several agencies including Homeland Security Investigations and the Attorney General’s Child Predator Unit.

Charges including two counts of criminal use of a communications facility, unlawful contact with a minor, obscene and sexual materials and failing to provide registration information were not prosecuted.
