FORT MYERS, Fla. - The U.S. Marshals have taken over the manhunt for one of Lee County's most wanted fugitives. This week, prosecutors filed federal charged against Wesnel Isaac.

The documented gang enforcer is charged with three counts of Second Degree Murder. He's been on the run since 2007. According to court records, the Lee County Sheriff's Office asked the marshals to adopt the arrest warrants.

The brutal triple murder shocked the area in September 2007. Willard Graham, Robert Barcklay and Scott Highfill were found dead inside an abandoned car in Lehigh Acres. They had been kidnapped from Graham's home in Bonita Springs, taken to rural Lehigh Acres and shot in the head.

Four men were charged and three are behind bars. But Isaac escaped.

Isaac is also wanted for home invasion and attempted felony murder. Authorities say he committed those crimes the week before the alleged murders.

Authorities have received several tips on Isaac's whereabouts through the years and they all point to Haiti.

On April 25th, authorities interviewed Isaac's girlfriend Angel Beard in Port Charlotte. Beard and Isaac have two children together. She admitted to speaking with Isaac's relatives on a regular basis. She told detectives, "you all know he is in Haiti."

Isaac is a documented member of the Zoe Pound Gang. At the time of the murders, the violent Haitian street gang controlled much of the drug activity in North Fort Myers. Isaac's job, according to authorities, was that of the enforcer.

Law enforcement eradicated that gang from southwest Florida. But there's still one more crucial arrest they want to make.
