The family of a Crest-view, Fla., man missing since August is asking for the public’s help in locating him after many posts on social media about seeing his truck in Andalusia.

Brett Stephen Henley, 25, has not been in contact with family or friends since Aug. 23, according to the Okaloosa County, Fla., Sheriff’s Office. He was reported missing by his mother.

Henley’s cousin Ryan McCurley has been monitoring comments on the OCSO’s Facebook page. He said Friday that several Andalusia residents reported seeing Henley’s white 2008 Chevrolet Silverado with Florida License Number G666KL around town. He hopes more information can lead to the location of his cousin.

Michele Nicholson, the OCSO’s public information officer, said her department is aware of the sightings and encourages residents to report other sightings.

“We don’t know why Mr. Henley is missing,” Nicholson said. “It is believed he could be in danger, either to himself, or by other means, so there is a concern for his safety. His family say that it’s not like him to be gone without any contact with his family.”

Henley is 5 feet 8 inches tall and weighs approximately 140 pounds. He has black, close-cut hair and brown eyes. He also has multiple tattoos including a pirate head and “Dead Men Tell No Lies” on his left arm, and a screw and nail on his calves.

Anyone with information on Henley’s whereabouts is asked to contact the Okaloosa County Sheriff’s Office at 850.651.7400.
