Police Searching for 2 Suspects After Response to Drug Laboratory in Brentwood

Drug Laboratory in Brentwood

At approximately 9:15 pm Tuesday, the Walnut Creek Bomb Squad responded to the City of Brentwood on a report of a hazardous materials call.

The incident was at Shasta Daisy Drive where the Contra Costa County Sheriffs Office was clearing a home when they located something explosive. This prompted the item to be transported to the parking lot of the Brentwood Police Department where it was allegedly detonated.

It was also stated a portion of the neighborhood was evacuated as a precaution. The search was possibly related to organized crime ring who have targeted local businesses.

The Contra Costa County sheriff Office has not released any information on the incident which prompted a CONFIRE response of 5 engines, a battalion chief, AMR, County Hazmat and Brentwood Police. CONFIRE was on scene for 4.5 hours.

Thursday UPDATE: Suspect Arrested at Drug Laboratory

On Tuesday, March 26, 2024, at about 9:52AM, detectives from the Contra Costa Sheriff’s Office served a search warrant at a residence on the 800 block of Shasta Daisy Drive in Brentwood.

During the search, they found a DMT (Dimethyltryptamine) manufacturing laboratory. While processing the lab, a team from the Contra Costa Hazardous Materials Program found a possible explosive compound stored in three containers.

The Walnut Creek Police Department Bomb Squad responded to the location. Officers suspected the compound was TATP (Triacetone Triperoxide), which is a highly volatile explosive compound. It was determined that two of the containers could be moved to another location for detonation, while one needed to be detonated in place. Nearby residents were evacuated.

The three containers were later detonated without incident. One person was arrested: 29-year-old Jonathan McCarthy. He was booked into the Martinez Detention Facility for an outstanding arrest warrant for parolee at large. The Sheriff’s Office is still looking for two suspects:

  • 44-year-old Maxwell Hayworth of Brentwood
  • 42-year-old Danielle Kumerow of Brentwood

Both are wanted for burglary, narcotics violations, possession of an explosive device, and child endangerment.

The investigation is ongoing. Anyone with any information on this incident or the location of the suspects is asked to contact the Investigation Division at (925) 313-2600. For any tips, email: [email protected] or call (866) 846-3592 to leave an anonymous voice message.

The Sheriff’s Office would like to thank the following agencies for their assistance: Walnut Creek Police Department Bomb Squad, Brentwood Police Department, FBI, JTTF (Joint Terrorism Task Force), CON Fire, AMR, and Contra Costa Hazardous Materials Program.

Last week, Brentwood officers were dispatched to a car accident that occurred on O’Hara Avenue near Baldina Drive. When officers arrived on scene, one of them immediately noticed a gun holster lying on the floorboard of one of the involved cars.

Officers determined the driver, identified as 44 year-old Maxwell Hayworth of Brentwood, was a convicted felon and in possession of a loaded gun, which is prohibited. Officers also located a large amount of prepackaged drugs, ziplock bags, approximately $2,000 in cash, shaved keys which can be used to open mailboxes or steal cars, as well as several license plates which did not belong to Hayworth.

Hayworth was placed under arrest for being a felon in possession of a firearm, Possession of drugs for sale, Possession of burglary tools, and other related charges. He was transported to the Martinez Detention Facility for booking.

This incident serves as a stark reminder that what may seem like routine calls for law enforcement can quickly escalate into uncovering serious criminal activities. The vigilance and thoroughness displayed by our officers in this case reflect their commitment to maintaining public safety and addressing criminal behavior within our community.

Am I reading this article correctly?
On January 17th Maxwell Hayworth was arrested by Brentwood PD for “being a felon in possession of a firearm, Possession of drugs for sale, Possession of burglary tools, and other related charges. He was transported to the Martinez Detention Facility for booking”.

On March 26, two months after his last arrest, he is again the subject of a drug manufacturing investigation.
I’m guessing he didn’t have to spend much time in Martinez and probably back in business within weeks.

I realize that our District Attorney’s office is a pretty weak institution but I would’ve guessed (wrongly) that a felon arrested with a firearm and prepackaged drugs for sale would’ve been in jail for at least six months, not out and about in our town manufacturing more drugs weeks later.

I read it the same way. Soros funded DAs like Becton need to GO! They are ruining our state and our country.

… and having all these agencies responding to this call will be costly to the city of Brentwood (CONFIRE response of 5 engines, a battalion chief, AMR, County Hazmat, Brentwood Police and Walnut Creek Bomb Squad

Brentioch, remember when Brentioch didn’t have Meth?

No. This entire region has had meth for forever. Only the name has changed. Stop with that nonsense.

This is not acceptable. I mean how is it so? The city, & the cops would rather go after a man making hamburgers in his garage to support his family temporarily, or an old lady who forgot her car registration tag needed to be put on her license plate. The priorities this STATE seems to follow, absolutely are insane and the EAST BAY is out of control with CRIME. It doesn’t help with places like Antioch who don’t get any help from their mayor nor do they have a big enough police force.. Or how bout on a bigger level….. What about that lady who calls herself the DA? She gives two hoots about putting the right people behind bars! Man! Have you people had enough yet???? Better figure out what is causing it…. VOTE DIFFERENTLY NEXT TIME! WAKE UP!
