Brandon Michael DeGuzman was 21 and a resident of El Cajon, California when he was shot and killed on September 24, 2016. The killing took place at his family home in the Bostonia community, where his body was found in the front yard after a violent confrontation tied to a minor drug debt.

DeGuzman offered an uncle’s AR-15 as payment; Gunner instead shot DeGuzman in the head and took the rifle. Gunner had a documented history of violent convictions and had been released from prison three months before the killing. He later received a sentence of 40 years to life for first-degree murder plus enhancements for firearm use and prior serious felonies.

Klingensmith pleaded guilty to voluntary manslaughter, possession of methamphetamine for sale, and two weapons charges and was sentenced to 15 years. DeGuzman’s mother, Michelle Gary, spoke in court about the deep bond with her son and the void his death created.

Did anyone in the Bostonia area have contact with Brandon in the days before September 24 who has not yet spoken publicly?
