Mark Wheatherington was a Palm Beach County Sheriff he flew the Sheriff's helicopter and his flight partners first name was Steve, don't remember his last. Mark was the leader of the PBSO SWAT team for a while. Mark lived in Loxahatchee south of Collecting Canal between D and E Road. None of those swat guys could shoot long range, they wanted to but wouldn't put the time in. Mark was a big guy, 6'6" built like a wedge, strong as a gorilla. First look at him you'd thought he lived at the gym. His wife was a PBC school teacher. Mark had to have his knees replaced. Climbing in and out of that helicopter and being cramped among growing pains from sports. They decided to retire and move to Tennessee.
On a curb and concrete note, do you know Jody Brooker? I worked for Bob Luke for 20 years and my BIL was Mark Durand.
