One person was killed and another was at the hospital in critical condition following a shooting early Thursday morning in Hacienda Heights.
Authorities say both victims, a man and a woman in their early to mid-20s, were sitting in their car on the side of the road in the 3000 block of Turnbull Canyon at about 1 a.m. when a shooter approached them and opened fire.
"First they shot through the driver's side, then they walked to the passenger side and fired through the passenger side," said Lt. Robert Westphal with the Los Angeles County Sheriff's Homicide Bureau.
