MADISON, Fla. – Agents with the Florida Department of Law Enforcement and the Federal Bureau of Investigation have announced a combined reward of $50,000 for information leading to identification, arrest, and conviction of the persons responsible for the abduction of 7-year-old Bryan Williamson of Madison, Florida.

The child was kidnapped from Gibson Trailer Park on April 17, 2016 between 5:30 and 6:30 p.m. and dropped off in Jacksonville between 5 and 7 a.m. on Monday, April 18, 2016.

“We have physical evidence in this case allowing investigators to quickly rule out potential suspects from the tips coming in,” FDLE Special Agent in Charge Mark Perez told WCTV. “Someone knows something and we are waiting for that one tip to tie the case together. No piece of information is too small; please call the tip line with any information.”

Authorities believe Bryan was abducted by a dark-skinned, possibly black or Hispanic, male driving a black or dark colored four-door sedan, possibly a Chevy.

Investigators are asking homeowners and business owners in the area of Northwest Gibson Trailer Parkway in Madison, Florida, to notify them if they have any surveillance video from Sunday evening. Likewise, home and business owners in the area of Hammond Blvd. in Jacksonville are asked to provide any surveillance video they have from Monday morning.

Additionally, authorities want to be notified of any unusual sale or alteration of a black or dark colored four-door sedan since Monday morning.  No piece of information is too small.
