A juvenile passenger died from injuries they sustained in a head-on collision on Highway 84 near Sunol on Sunday morning, marking the fifth traffic fatality in 10 days for the greater Tri-Valley.
The situation unfolded at about 6:05 a.m. Sunday when the reports first came in about a serious two-vehicle collision on Highway 84 east of the Interstate 680 interchange, according to Officer Tyler Hahn of the California Highway Patrol's Dublin office.
The driver of a white Chevrolet Tahoe in the westbound lane decided to turn to the left into the eastbound lane for unknown reasons. "As a result of the unsafe turning movement, the front of the white Chevrolet Tahoe collided head-on with a black Dodge Charger," Hahn said.
Both drivers, as well as three passengers in the Charger, were transported to area hospitals with major injuries, including two who were airlifted by helicopter. One passenger from the Charger succumbed to their injuries later Sunday morning, according to Hahn.
The decedent's name has not yet been released by the Alameda County Coroner's Bureau, but Hahn confirmed the victim was a juvenile.
The four surviving parties remain under treatment for major injuries, according to the officer.
The circumstances of the collision remain under investigation, although alcohol and drug impairment are not suspected factors at this time, Hahn said. He encouraged any witnesses to contact the CHP-Dublin office at 925-828-0466.
Sunday morning's fatality represents the latest in a string of five deadly car crashes in the greater Tri-Valley since Aug. 26 -- all within CHP-Dublin's investigative jurisdiction.
