BLOOMINGTON — An off-duty Victorville Sheriff’s deputy shot and killed his older brother during a family party that turned violent Saturday night, officials said.

According to a San Bernardino County Sheriff’s Department statement, the deputy, 26-year-old Humberto Miranda, shot his brother, 28-year-old Israel Miranda, after Israel armed himself with a knife during an argument and assaulted family members.

The shooting occurred about 9:12 p.m. when Fontana deputies responded to calls of gunfire heard in the area of Magnolia Street and Marygold Avenue.

Deputies arrived at a residence in the 9800 block of Magnolia Street and found several people in the front yard, including Israel who was suffering from gunshot wounds.

Another man, 24-year-old Sergio Miranda, was found with a cut to his hand but refused medical treatment.

Israel was transported to Arrowhead Regional Medical Center where he was pronounced dead.

Homicide investigators “learned that Israel was on active parole and had a history of violence” and that the argument occurred during the family party.

A court records search found Israel had felony convictions for assault with a deadly weapon and resisting an executive officer.

Humberto is a Sheriff’s deputy assigned to the Victorville station.

Sheriff’s spokesperson Cindy Bachman said the deputy is not on administrative leave, but is taking a few days off.

The investigation is being submitted to the District Attorney’s office for review.
