A jury convicted a 26-year-old Glendora man of attempted murder, robbery, burglary and a host of other criminal charges on Wednesday for a 2015 crime spree including a home-invasion robbery in San Marino and a shooting in Glendora, authorities said.
A Pomona jury deliberated for one day for finding Clayton Ruben Addleman guilty of 13 criminal charges, according to Los Angeles County District Attorney’s Office spokeswoman Sarah Ardalani. He was convicted of three counts of burglary with a person present, attempted murder, residential robbery, grant theft auto, grand theft, identity theft, forgery related to identity theft, assault with a firearm, possession of a firearm by a convicted felon, possession of ammunition by a convicted felon and petty theft. Jurors also found true the special allegations that Addleman personally used a firearm in the crimes.
He faces a maximum penalty of 52 years to life in state prison when he returns to the Pomona branch of Los Angeles County Superior Court for sentencing on Aug. 3, Ardalani said in a written statement.
Prosecutors said Addleman shot at, but did not strike, another man in his hometown of Glendora on Dec. 27, 2015.
“During the investigation, law enforcement believed Addleman may have been the suspected shooter,” Ardalani said. “Two days later, police located the defendant and took him into custody.”
Investigators soon found that Addleman was also responsible for a home-invasion robbery that occurred on Dec. 29, 2015, at a home in the 500 block of Huntington Drive in San Marino.
In that crime, “Addleman armed himself with a handgun, broke into the San Marino home while the residents were inside and then attempted to steal the victims’ vehicle before ultimately fleeing the scene,” according to Ardalani.
A terrified female resident hid in the closet during the home invasion, San Marino police officials said.
When arresting Addleman, police discovered ammunition, as well as checks and identifying documents in the names of other people, Ardalani said.
Addleman was already on probation stemming from another criminal case when he was arrested in connection with the current one.
He was convicted of possession of drugs for sales and possession of a firearm in by a felon in July of 2015, three months after police searched his Starcrest Drive home and discovered two rifles, four handguns, ammunition, 1,000 Xanax pills and a scale, Glendora police Lt. Matt Egan said at the time. Investigators has gone to his home to serve a warrant related to a previous conviction for possession of illegal fireworks in 2014.
Addleman received 180 days in jail and three years of probation for the 2015 gun and drug case, court records show.
