Police used pepper balls, drones and robots in an attempt to talk him down. During this time the suspect was also on the phone with the 911 operator.Despite many efforts, the man remained inside the car. Deputies later responded and found him with “sustained injuries from a self-inflicted gunshot,” authorities said. He was declared dead on the spot. His identity has not been released.The video of the deputy using his phone during the operation has gone viral, with many people questioning his behavior during such a critical situation. Authorities have not confirmed what app he was using, but it appears it was a dating app.
