A St. Joe Beach man was arrested Thursday on charges relating to two sexual batteries and possession of child pornography.

Clark Gilbert Downs, 69, was arrested as the result of an investigation that began March 18, according to the Gulf County Sheriff’s Office.

That investigation stemmed from an allegation of sexual assault and led investigators to evidence of a second incident four years ago.

The victims in each incident was under the age of 18.

Sheriff’s investigators as well as special agents with the Florida Department of Law Enforcement and analysts from the FDLE Computer Crime Center executed search warrants at Downs’ home Thursday.

A warrant for Downs’ arrest had been secured based on evidence Downs was using a computer to seduce, solicit, lure or entice a child, according to the GCSO.

Downs is alleged to have used Facebook Messenger to receive and solicit inappropriate photographs of the victim, who he knew.

While serving the search warrant, and taking Downs into custody, investigators seized multiplie computers and electronic devices for additional analysis.

On a computer at the scene, investigators found photographs taken in November 2014 of the second victim.

The photos corroborated information provided by the victim.

That led to additional charges against Downs of sexual battery on a person 12 years or older, lewd or lascivious molestation of a victim 12 years or older and 11 counts of possession of child pornography.

Additional charges are anticipated.

Downs was booked into the Gulf County Detention Facility and later released on $110,000 bond.
