Yesterday, at about 9:38 AM, Delta Station Deputy Sheriffs responded to a home on the 1700 block of Green Acres Lane in Knightsen, in an unincorporated area east of Brentwood, regarding a report of spousal abuse.
The female victim reported that she was held hostage overnight by an ex-boyfriend who sexually assaulted her, threw her on a coffee table, tied her to a chair with duct tape, and poured gasoline on her. The suspect is identified as 44-year-old Eduardo Martinez of Bay Point. He also threatened to burn down the house with her in it. The victim, who said Martinez had a shotgun and pistol, also reported that he made threats to shoot law enforcement and said he did not want to go back to jail. The victim, who is not being identified, was able to escape from the house.
Deputies set up a perimeter around the house and made numerous announcements for Martinez to come out. There was no response. The Sheriff’s Office SWAT Team and Hostage Negotiation Team (HNT) responded to the location at about 12:40 PM.
HNT communicated with Martinez during the afternoon and into the evening asking him to surrender. Martinez fired the shotgun into the ground and shot at Deputies several times during the day and would not give up.
At about 8:58 PM, Martinez came out of the house advancing on deputies and fired his shotgun at SWAT Team members. Three of them were struck. Deputies returned fire hitting the suspect. Martinez was later pronounced deceased at the scene.
One Deputy was struck in his chest but was saved by his bulletproof vest. Another was hit in his head by shotgun pellets and the third was shot in his arm. All have been treated and released from the hospital.
Martinez has had extensive contacts with law enforcement. His previous arrests include: domestic battery, spousal abuse, making criminal threats, false imprisonment, obstruction, receiving stolen property and multiple counts of driving under the influence.

You keep reporting Knightsen as the location where this happened. It’s actually, Brentwood. Eduardo was also living at that address for some time. Flagg just didn’t want people to know he was there. This isn’t the first time Eduardo tied Flagg up. She continued to allow him over there after being warned not to.
Gordon,
Thank you for reading the Herald and taking the time to comment, as well as that additional information.
It’s actually outside the boundaries of the City of Brentwood, it’s in an unincorporated area and Knightsen is how the Contra Costa County Sheriff’s Office describes the location.
Please note the name and title of the person who wrote it.
