Week in Review : MAJOR EVENTS, IMAGES AND PEOPLE IN ORANGE COUNTY NEWS : AT THE SCENE : Car Jumps Curb, Kills Boy, 9, Riding Bicycle

The calm of a residential Irvine neighborhood was shattered when suddenly a westbound car on Bryan Avenue turned left onto Yale Avenue and jumped the curb where 9-year-old Jesse Paul Joe R. Sullano was bicycling with friends.

“As the car completed the turn, it drove up onto the sidewalk,” Irvine Police Lt. Al Muir said of the Friday morning collision. The car continued for about 75 yards, knocking down trees and striking Jesse and another boy. Two other boys narrowly escaped injury.

But Jesse, a 9-year-old Filipino living in Irvine with his aunt and uncle, Bo and Benjamin Ros, was killed. The Roses’ son, Giancarlo Juan, also 9, was injured.

Three men inside the car fled on foot.

Within an hour of the accident, police had arrested three suspects. Booked at Orange County Jail on suspicion of vehicular manslaughter and felony hit and run was Culmaro Urena, 23, of Santa Ana, a Mexican national who does not hold a California driver’s license, police said. Bail was set at $50,000.

Jorge Enrique, 16, and Juan Carlos Garcia, 27, both identified as passengers in the car and Mexican nationals living in Santa Ana, were detained at Orange County Jail as material witnesses. However, they were not booked.

A police spokesman said the detention was a precaution because Enrique and Garcia are Mexican nationals, and “there is fear that they will flee the area.”

Hours after her nephew was killed, a subdued Bo Ros in her living room said: “You can’t find a better place than Irvine, especially for kids. I’ve always felt so safe here, and then this happened.”
