A 47-year-old Weston man left a suicide note in his car and then fatally shot himself at the Arizona Shooting Range in Lauderdale Lakes.

Authorities did not release the man's name, but did confirm details in the incident Friday morning.

"He shot himself there at the gun range," said Sheriff's office spokesperson Veda Coleman. "He did leave behind a note."

Employees at the North State Road 7 business declined to speak about the matter, and a man arriving shorly afterward to shoot said those few customers already on the scene were stunned.

"The witnesses were kind of quiet, I guess reflective -- like they couldn't believe what had happened," Cooper City resident David Wilpon told the Sun-Sentinel. "[Employees] would just say, 'There was an accident here.'"

Suicides at gun ranges are increasingly common as law does not require background checks on those who rent guns, only on purchasers. In one three-month period in 2009, four people committed suicide at gun ranges in the Orlando area alone -- prompting some Florida ranges to stop renting guns altogether.
