CLEARLAKE, Calif. – The Clearlake Police Department on Tuesday executed a search warrant at the home of a convicted felon and sex offender, finding a cache of weapons that included AR-15 semiautomatic rifles and a machine gun.

Sgt. Rodd Joseph said the search warrant was served at the home of 53-year-old Robert David Cooper early Tuesday.

Joseph reported that on Monday the Clearlake Police Department was contacted by officers with the Fresno Police Department, who reported that they had arrested Cooper for numerous firearm violations.

Cooper is a convicted felon and a registered sex offender and may not lawfully possess firearms or ammunition, Joseph said.

The Fresno Police Department officers had obtained information that Cooper had additional firearms and ammunition concealed in hidden compartments in his Clearlake home, according to Joseph.

With that information from Fresno Police, Joseph said Clearlake Police Det. Ryan Peterson was able to obtain a search warrant which was endorsed for night service.

On Tuesday just before 1:15 a.m. Clearlake Police officers, along with a Lake County Sheriff’s deputy, served the search warrant on Cooper’s residence located in the 16100 block of 36th Avenue in Clearlake, Joseph said.

Joseph said that during service of the search warrant a number of illegal weapons, ammunition and narcotics were located. Most of the weapons and ammunition located were found in hidden compartments within the home, corroborating the information obtained from the Fresno Police officers.

Some of the weapons located and seized include three handguns, an automatic “Uzi-style” machine gun, two AR-15 semiautomatic rifles, a large number of high capacity magazines for both the rifles and handguns, a Taser, hundreds of rounds of ammunition and a small amount of methamphetamine, according to Joseph’s report.

Since Cooper is in custody in Fresno County, numerous felony charges will be filed with the Lake County District Attorney’s Office, Joseph said.

Joseph said the Clearlake Police Department is committed to removing illegal firearms and weapons from those who may not possess them.
