JACKSONVILLE, Fla. -- A Clay County Sheriff's Office Detention Deputy was found dead in his home after the Jacksonville Sheriff's Office performed a wellness check.

According to CCSO, 46-year-old Brian Cason did not arrive to work at the Clay County Jail for his shift Wednesday night. Coworkers became concerned and contacted JSO.

Once JSO arrived at Cason's home, deputies discovered that Cason was dead.

At this time, preliminary reports by JSO suggests there were no signs of foul play, however, the Jacksonville Medical Examiner will determine the cause of death.

Cason had worked with the Clay County Sheriff's Office since July 2012. His coworkers and supervisors said he was a "hard-working, helpful, quiet man." Before working with CCSO, Cason worked for the Florida State Prison System.

JSO will take the lead in the investigation of Cason's death. At this time, it is considered, "undetermined" while everyone awaits the Medical Examiner's report on the official cause of death. He was married with adult children and his relatives were notified overnight.

Visitation for Caston will be held Monday, Jan. 20 from 1 p.m. to 2 p.m. at Jacksonville Memory Gardens in Orange Park. Funeral and burial will be held immediately after also at the Jacksonville Memory Gardens.
