Five juvenile suspects have been arrested in connection with the April 2 shooting of a San Jose paramedic, Oakland police chief Howard Jordan announced Tuesday.
Quinn Boyer, 34, was shot multiple times before he crashed his car down an embankment at Keller and Handsom avenues in the Oakland Hills.
"I am deeply, deeply concerned by the fact that the persons responsible for this man's murder ranged in the age of 14 to 16 years old," Jordan said. "That is unacceptable. This is a disturbing trend that we've noticed here in this city."
The oldest of the five suspects is 16, two are 15 and two are 14, according to Public Information Officer Johnna Watson. All are Oakland residents.
Charges include homicide, robbery and carjacking. Oakland police have not discussed with the District Attorney whether the boys, who are not believed to be members of a gang, will be charged as adults.
An initial arrest was made Monday night, which led to the arrest of the other four suspects, including the boy believed to be the lone triggerman, according to Lt. LeRonne Armstrong.
"The investigation is ongoing so there might be other individuals that might come up in the investigation, but at this time we have the individuals we believe were involved in this crime," Armstrong said.
Boyer, a Dublin resident, was leaving his sick father's home at the time and pronounced dead on April 4. His funeral was held Tuesday.
Oakland police did not make public a possible motive with the investigation ongoing.
Boyer had served as a paramedic since 2008 and in a full-time capacity with Santa Clara County Ambulance since 2011.
He had recently been accepted into the physician's assistant program at Stanford University.
He is survived by his wife, an Oakland paramedic, and family, which released a statement the day after he died urging anyone with information about the shooting to contact Oakland police.
He also served as a Big Brother and as a volunteer at the Order of Malta Clinic in Oakland.
Boyer's family says they're humbled by the love and support shown by their extended EMS family.
Fellow paramedics at Santa Clara County EMS describe Boyer as being extremely well-liked.
The company's employees faced another tragedy two years ago when fellow paramedic Bryan Stow was severely beaten at Dodger Stadium in Los Angeles after a San Francisco Giants game on Opening Day. Stow suffered brain damage and his treatment is ongoing.
Oakland police said anyone with information about the shooting is asked to call the homicide unit at (510) 238-3821.
