Norwalk police are still investigating why a Benedict Avenue resident, 44, decided to shoot himself Monday morning in Jaycee Park.
School officials put Pleasantville Elementary School, which is located near the park, on lockdown after school officials were notified.
William Garman, 44, 100 block of Benedict Avenue, died shortly after shooting himself in the chest with a .45-caliber pistol, said Norwalk Police Capt. David Light.
Norwalk police responded to the incident at 8:20 a.m. and found Garman near a picnic table with the single gun shot wound to his chest.
Police called an ambulance when they determined Garman was still alive.
"EMS started CPR and he had a slight pulse so they shipped him to Fisher-Titus, but we later found out he was dead," Light said.
Norwalk Schools Superintendent Wayne Babcanec said police contacted school officials after they received a 911 call from Garman's wife.
Light said police had no reason to believe the school was in any danger.
"It's just in the immediate vicinity," he said. "Those are the precautions we're going to take."
Garman's wife told dispatchers her husband called her from the park and told her what he was planning to do.
Norwalk police said they responded within three minutes of the call and found Garman on the ground.
"He apparently had been depressed," Light said. "His wife said he talked about suicide, but she didn't think he was serious."
Police found no witnesses, though the apparent suicide occurred as children walked to school.
Classes at Pleasantville Elementary were not canceled, but the lockdown meant teachers and students remained locked in their classrooms until the situation was sorted out.
Police cleared the scene by 9:20 a.m.
Light said Garman had no criminal record.
"Suicides are hard to understand," Light said. "Sometimes they talk about it prior to. Sometimes they never talk about it and their are no red flags. It's hard to understand."
