SAN JOSE — Two of the three people who were killed in shootings Sunday were teenage boys, the San Jose Police Department confirmed Monday.

While authorities would not release their names, police said in a statement that both are believed to be between 15 and 17 years old. The two were found shot early Sunday night in East San Jose. Later in the evening, a third man was shot to death in South San Jose.

Suspects, the statement added, have not be identified in either shooting.

The three fatalities brought San Jose’s homicide total this year to 19. It was, San Jose Mayor Chuck acknowledged, a bad Memorial Day holiday weekend for the city.

“One homicide is too many,” said Reed Monday following a remembrance ceremony at Oak Hill Memorial Park. “We’re up to 19 now, and that’s far too many.

“But people should know that our police department does a great job investigating, catching the bad guys and putting them in a jail. “They’re putting in a lot of overtime to make sure that happens.”

Just before 6:30 p.m., officers responded to a 911 call reporting two people shot on Rinehart Drive at Clogston Court, not far from a large shopping center on McKee Road in East San Jose. Police Lt. Tim Kuchac said patrol officers found the two victims on the sidewalk in front of a row of townhouses.

“It was a double-homicide in broad daylight,” Kuchac said Sunday night.

He added that both victims apparently were shot with a handgun. One died at the scene while the other was taken to a hospital, where he was pronounced dead.

No motive was immediately known for the shooting, and Kuchac could describe one suspect only as a “Hispanic male, younger, on a BMX bicycle.”

Neighbors said the victims possibly were students at nearby Independence High School. But Monday, police remained tight-lipped. In the statement, authorities said that the medical examiner’s office was still working to identify the victims and notify relatives.

Also, police said it was unknown if the shootings were gang-related, although a department spokesman said Sunday that the neatly kept, working-class neighborhood was not known for gang violence.

Later, at 10:11 p.m. police responded to another 911 call in the 100 block of Hayes Avenue in South San Jose where an unidentified man had suffered at least one gunshot wound. He was pronounced dead at the scene about 15 minutes later. The victim’s name also has not yet been released and police did not know if that shooting was gang-related.

Early Monday morning, the neighborhood was quiet. The only sign that a shooting had occurred a few hours earlier was torn police crime tape that had blocked the sidewalk along Hayes Avenue in front of the Orchard Park Apartments.

Also, at 12:14 a.m. Monday, police received a report of a man brandishing a gun in a parking lot of the 300 Black of North Jackson Avenue. A patrol officer spotted the suspect’s vehicle and followed for several blocks before losing it. A short time later, it was found unoccupied on Commodore Drive, but police were unable to locate the man.

At 6 a.m., police received a call from an employee of a business in the 900 block of Lundy Avenue about seeing the suspect, and he was arrested in possession of a handgun. The suspect was admitted to a local hospital for injuries he sustained when he crashed the car, which was stolen, on Commodore earlier.

Anyone with information about either shooting is asked to call police at 408-277-8900.
