DIAMOND BAR - A crash caused by a 21-year-old wrong-way driver going eastbound on the westbound Pomona (60) Freeway in Diamond Bar killed six people and injured at least one other person, authorities said.
The driver, Fontana resident Olivia Culbreath, was arrested on suspicion of felony drunken driving and felony manslaughter, CHP Officer Jennifer Cassidy said.
Culbreath, listed in serious condition, was being treated at Los Angeles County/USC Medical Center for a fractured femur and ruptured bladder, Cassidy said.
The crash happened at 4:50 a.m. on the westbound Pomona Freeway north of Diamond Bar Boulevard, according to California Highway Patrol officials.
Cassidy confirmed at least four fatalities. Los Angeles County Coroner's Lt. Fred Corral said two people taken to UCI Medical Center later died.
Corral said four females and two males died as a result of the multi-vehicle crash. One of the injured was flown by helicopter to a hospital, County fire dispatch Supervisor Kyle Sanford said.
The coroner's office released the ages and genders of three of those killed: Two were 24-year-old women -- one from Rialto and the other from Chino -- the third was a 47-year-man, whose hometown was undetermined, Corral said.
Their names were withheld pending notification of kin, he said.
