An off-duty sheriff’s deputy fatally shot his brother, an allegedly knife-wielding parolee, during a family gathering Saturday in San Bernardino County, officials said.

Deputies responded at 9:12 p.m. to reports of a shooting at a residence just off Interstate 10 in the Bloomington neighborhood, near Fontana, according to a news release from the San Bernardino County Sheriff’s Department.

There, they found a man suffering from multiple gunshot wounds. He was pronounced dead at a hospital.

The dead man was identified as Israel Miranda Jr., 28, of Bloomington. He was described as a parolee “with a history of violence.”

The sheriff’s department said he had been shot by his brother, Humberto Miranda, 26, of Fontana, a San Bernardino County sheriff’s deputy assigned to the Victorville station. He was off-duty at the time.

Investigators say that an argument broke out in the front yard of the home and that Israel Miranda attacked several of his relatives with a knife.

Another brother, Sergio Miranda, 24, of Bloomington, suffered a cut to his hand, said the release.

The news release named Israel Miranda as the suspect in an attempted murder/homicide investigation. Sergio Miranda and Humberto Miranda were described as victims and were not arrested.

Investigative information on the incident will be submitted to the San Bernardino County District Attorney’s office for review.
