Memorial set for slain Oakland firefighter

A memorial for the Oakland probationary firefighter who was fatally shot in San Jose is scheduled for place Saturday, authorities announced Tuesday.

The service for 30-year-old Jake P. Walter is to begin at 11 a.m. at the Oakland Scottish Rite Center, city officials said.

Walter, who graduated from the Oakland Fire Department Academy on April 22, was killed Thursday night after Oliver Juinio, 27, of San Jose, allegedly opened fire on him and four other off-duty firefighters outside the Gordon Biersch Brewing Co. in San Jose’s Japantown.

Walter was taken to a hospital, where he died. A 26-year-old firefighter, whose name was not released, was treated in the intensive care unit at Santa Clara Valley Medical Center in San Jose, and is recovering, officials said.

The firefighters were enjoying a night out when they were confronted by two or more men on the sidewalk during the Taylor Street Night Market, investigators said. Witnesses said from that confrontation, gunfire erupted apparently without warning.

Juinio was charged with murder and attempted murder in connection to the shooting.

According to court records, he has a criminal history out of Santa Clara County, with a burglary and attempted burglary conviction in 2010 and a drunk driving conviction in 2015.

Juinio’s prior felony record counts as two strikes under the state’s “three strikes” law, according to the Santa Clara County District Attorney’s office, meaning he will face significantly more prison time if he is convicted.
