Josh Mitchell was listening to rap music with his friend Sunday night, June 30, when he thought he heard fireworks.

When he turned the music down, he heard them again. This time, he said, he knew the sound wasn’t fireworks, but gunshots.

“You just don’t expect these things to happen this close to home,” he said.

Five people were wounded, none seriously, in a Yucaipa shooting that began as an afternoon argument at a mobile home park barbecue and ended with gunfire breaking out, authorities said, endangering dozens of people at the scene.

Three of the victims had arm and leg wounds described as non life-threatening, and two had graze wounds, San Bernardino County sheriff’s deputies said. The victims were identified as four men and one woman.

One person was been detained, but was not described Monday as a suspect.

A Chevrolet Trailblazer left the Mountain View mobile home park in the 12700 block of California Street late Sunday afternoon, according to deputies, and later returned. The SUV has since been found, they said.

The people inside the Trailblazer started arguing with family members at the barbecue, according to deputies, then left after threatening to kill them. They returned and a fight broke out with shots fired from a handgun, wounding the five people.

Deputies were called shortly before 10 p.m.

Witnesses had given to investigators photos they had taken of the Trailblazer.

At the time of the shooting there were “dozens of witnesses and involved parties at and around the fight,” deputies said, asking Monday that those who left before law enforcement arrived contact them.

Some may have videos of the shooting and argument, and deputies are asking to see those.

Mobile home residents on California Street, including Frances Johnson and Maria Rodriguez, also figured the noise Sunday night was from fireworks. After all, Rodriguez explained, the upcoming Fourth of July holiday made it a possibility.

“I thought somebody was popping M-80s,” she said.

By midday Monday, police had left the area and no signs of the shooting remained.

Anyone with information or evidence of the shooting is asked to contact the Yucaipa Sheriff’s Station at 909-918-2305. Anonymous tips can be made at 800-782-7463 or at www.wetip.com.
