Pierce County Sheriff’s Department (PCSD) Deputy Cooper Dyson died in the line of duty on Saturday, Dec. 21, as he was responding to help fellow deputies who were under attack.
The incident happened just after 3 a.m. when the PCSD received a 911 call regarding a 6-year-old disabled child who had been assaulted inside a residence on 113th Street South in Parkland, according to Sgt. Ed Troyer, the department’s representative.
The 911 caller also reported that there were multiple weapons in the home, KOMO reported.
Within one minute of arriving at the scene, the two deputies who responded to the call radioed for emergency backup and advised that they were under attack, Troyer said.
Deputy Dyson, 25, was the first deputy to race to their aid. As he was responding, his fellow deputies radioed that they were still in a fight and the suspect was trying to get to a shotgun in the home.
Investigators said they believed Deputy Dyson hydroplaned on the wet roadway as he was desperately racing to assist his officers.
His patrol car barrel-rolled and went airborne before it slammed into a building on 112th Street East and burst into flames.
Deputy Dyson, who was trapped inside his car, died at the scene.
The domestic-violence suspect that the other PCSD deputies were fighting with was ultimately arrested, according to The Seattle Times. The deputies did not suffer any significant injuries.
“This is a tremendously sad loss. Our deputy was responding to help other deputies in a dangerous domestic violence situation. It is another hard reminder of the dangers and difficulties our Deputies face,” Pierce County Sheriff Paul Pastor said in a press release.
Dyson left behind his 2-year-old son, as well as his wife, who is pregnant with their second child, according to the PCSD.
