Richmond Man Charged With Felony Illegal Weapons Possession

Office of the Attorney General

From the Office of the District Attorney:

Martinez, California – The Contra Costa District Attorney’s Office filed a 21-count felony complaint against a Richmond man for possessing a large cache of illegal weapons, high-capacity magazines, and homemade explosives.

Lawrence Robert Hansen, 68, of Richmond is in custody after he was arrested on an outstanding warrant on March 17th by Richmond Police. Hansen is also listed on the Armed and Prohibited Persons System which tracks individuals who are barred from owning or possessing firearms.

Between 2022-2023, Hansen made several violent firearm-related threats to medical staff at a Walnut Creek clinic while seeking treatment. Staff members reported those threats to Walnut Creek Police on September 18th, 2023. In a separate incident, Hansen was transported to a hospital in Walnut Creek on September 26th, 2023, for a medical issue. During an examination, a staff member saw that Hansen had a handgun (later determined to be loaded) in his waistband area. The weapon was taken from Hansen and police were informed.

Because of the legal prohibition against Hansen possessing firearms, as well as threats made to medical employees, members from the Contra Costa Anti-Violence Support Effort Task Force, California Department of Justice’s Bureau of Firearms, and Contra Costa County Probation Officers searched Hansen’s residence with a court-ordered warrant in Richmond on January 31, 2024. During the search, agents found 11 machine guns, more than 130 handguns, 37 rifles, 60 assault rifles, 7 shotguns, 3000 large capacity magazines, several grenades (inert), homemade explosives, incendiary ammunition, and around one million rounds of ammunition.

Hansen was arraigned on March 18th in Martinez. He entered a plea of not guilty and is being held without bail in the Martinez Detention Facility. A preliminary hearing is scheduled for March 27th in Department 23 at 8:30 am.


    • I have friends that own into the low one hundreds of weapons, all former law enforcement. They collect for the beauty, functionality, diversity, etc. Me, I own six, all for different uses. The above guy has mental issues.

  1. So, 4 months passed between police notification and an arrest warrant for an arrest with a no-bail determination. Something is wrong in this system for a person deemed to be this dangerous.

  2. Misdemeanor weapon charges back in 2013 and was represented by the public defender. Interesting he has money for a —load of guns but we have to pay for his attorney.

  3. So thankful this played out the way it did. Collecting firearms is definitely a hobby but this seems extreme. Over 1 million rounds of ammunition? Ammo is currently .25-.45 cents per round. Guy should have sold it all and retired.
