On Monday, the Contra Costa County Sheriffs Office and District Attorney’s Office are continuing to investigate the officer involved shooting that occurred in Byron on Friday.
The autopsy took place Monday morning on the suspect, 49-year-old Michael Mallett. The cause of death is listed as multiple gunshot wounds.
The three Office of the Sheriff employees who discharged their firearms are:
- Sergeant Mark Johnson (hired in November 1998)
- Sergeant Shawn Welch (hired in December 2003)
- Detective Anthony Rossi (hired in October 2006)
All of them are assigned to the SWAT team.
On Thursday at about 10:06 PM, Deputy Sheriffs went to a home on the 2700 block of Hoffman Lane in Byron to serve an arrest warrant to Mallett. The $1.15 million dollar arrest warrant was for 12 counts of child molestation. The investigating agency was the Office of the Sheriff.
On Friday, deputies made contact with the Mallett who walked out of the residence with a firearm. He refused to comply with the Deputies and went back into the home and barricaded himself. Deputies were able to evacuate other occupants in the home. Negotiators arrived on scene and began to communicate with him. Negotiations were sporadic but Mallett continually talked about not surrendering, not putting his gun down and harming himself.
The Sheriff’s Office SWAT team was called out at 3 AM as negotiations continued. Numerous announcements were made into the house for the man to surrender.
At about 9:30 AM, chemical agents were deployed into the home. Mallett came out of a window armed with a handgun. He did not comply with commands to drop the weapon. He was shot when he raised the gun at Deputies. Deputies administered life-saving measures. He was pronounced deceased at the scene by the fire department.
The officer involved fatal incident protocol was invoked.
