Antioch Police Say Officer Shot in Head with “High-Powered BB-Type Firearm”


The Antioch Police Department offered more details into an incident that left one officer struck in the head by gunfire Monday evening in the 4500 block of Deerfield Way in the City of Antioch.

According to police, they were responding to a dispute between neighbors when a firearm was brandished. When police arrived on scene and the suspect came to the door, without warning, the officers were fired upon by the 32-year-old man.

At that point, aid was requested which led to a 5-hour standoff before his surrender.

Antioch Police Chief Tammany Brooks defended the response by multiple agencies because at that point in time, officers did not know what the officer was shot by.

“They didn’t know it was a BB-gun until he was in the hospital, he had blood all over his uniform, all over his face, there is no one who would have looked at him and known what the injury was. It was realistic to believe he was shot,” said Brooks. “The response was to an officer down and they believed he had been shot. That was an appropriate response in any situation. Based on the information we had at the time, it was not unrealistic response.”

Brooks further explained that if the incident occurred in another agency, they would also send assistance as needed.


Here is the press release issued by Antioch Police Tuesday afternoon:

On 11/5/18 at approximately 7:26 pm, a citizen called the Antioch Police Department to report that their neighbor (a 32-year-old male) threatened him with a firearm.  When officers responded, they contacted the reporting party and learned about an on-going dispute between the two neighbors. During this day’s incident, the victim and his neighbor were standing outside attempting to mediate the issues when another family member brandished a black semi-automatic firearm in a threatening manner.  The victim returned to his residence and called the police.  


When officers arrived, they learned about the dispute and the brandishing that happened just moments prior. As officers approached the suspect’s residence, he called out to them from an open upstairs window.  The officers identified themselves and their purpose for being there.  The suspect told them he would be right down.  Upon opening the front door, and without warning, the officers were immediately fired upon.  One officer was struck in the head and retreated to a parked vehicle. The officer’s injuries were visibly consistent with being struck by gunfire, and other officers at the scene reported that an officer had been shot. The suspect retreated into the house and closed the door barricading himself.  The victim officer began bleeding profusely and was quickly transported to a local area trauma center.   


Shortly afterwards, police supervisors arrived at the scene and a call for emergency support and mutual aid was requested. With the assistance of responding allied agencies, the scene was quickly contained and cordoned off.  Initially, a shelter-in-place was initiated for the immediate neighborhood while officers were attempting to establish contact with the occupants of the residence. 


The response to the Officer Involved Critical Incident included the Contra Costa County Sherriff’s Office, the Contra Costa County Fire Protection District, the District Attorney’s Office, and numerous local allied agencies.  The response provided valuable support to the Antioch Police Department’s SWAT Team, the Hostage Negotiation Team, the Investigations Bureau, and Command Staff.  


During preliminary negotiations with family members, it was learned that the 32-year-old suspect was refusing to surrender peacefully.  The barricaded suspect was home with his parents, and information developed that the suspect had a history of law enforcement contact in another city, which involved the possession and use of a black semi-automatic firearm that currently showed to be registered to him. 


During the standoff, one family member exited the house. One other family member did not exit, and it was unknown if they were being held against their will.  As the standoff continued, it was discovered that the injured officer sustained multiple non-life threatening injuries consistent with being shot by a highpowered BB-type firearm.  Once this information became known, Hostage Negotiation Team members continued to work with family members at the scene to build rapport with the suspect, which led to the peaceful surrender of the responsible and a successful resolution to the incident.


As the suspect was transported to the Antioch Police Department jail for booking, the Investigations Bureau took over the investigation with the assistance of senior inspectors from the District Attorney’s office. A search warrant was served at the location and two high-powered BB-type rifles were recovered along with a BB-type replica of a black full-sized semi-automatic pistol, BB ammunition, and live pistol ammunition.  


At the conclusion of the investigation, this case will be referred to the District Attorney’s office for the felony charges of:

  • PC 245(c), Assault w/a Deadly Weapon Other than a Firearm on a Peace Officer
  • PC 422, Criminal Threats
  • PC 417.8, Brandishing a Deadly Weapon at a Peace Officer.  


The Antioch Police Department wishes to express sincere gratitude for the outpouring of support and assistance during this critical incident, from the beginning through to its peaceful resolution.

  1. Frankly, most of us don’t care if it was a spit-wad at this point. Whatever you have to do to stop the guy, do that. Terrible for any officer to have to go through this. Serious injuries and even death are possible just from bb’s. No sympathy for this shooter. He got off easy.

  2. Yes, There is a difference between a
    “ firearm “ and a B.B. or Pellet gun. The latter is a deadly or dangerous weapon not a firearm. They must charge him correctly or he will get off with nothing. Now all we can hope for is that they give him the maximum for the charges filed.

  3. Way to go Antioch Police Department for doing such a fantastic job. Thank you for protecting our officers and the public at large. There should be no question that this was the right thing to do.

  4. The Antioch Chief of Police did the right thing in requesting outside help. What was this idiot doing with those high-powered BB=guns? What was he using this for? Sounds like a total nut case! I hope he is locked up for a very very long time. I’m sure the neighbors will appreciate it.

  5. Praying for the dear officer injured. Thank you all first responders for putting your life on the line for us.

    Can someone please tell me if the officer was officer Matt Allendorph?
