Two adults and two young children -- believed to be a family of four -- were killed Tuesday in a two-vehicle crash in the Palmdale area.
A sedan and an Antelope Valley Transit Authority van pool vehicle were involved in the collision, which occurred about 10:25 a.m. at Sierra Highway and East Avenue M.
According to coroner's Assistant Chief Ed Winter, three people died at the scene: a man about 20-25 years old; a woman about 20-25; and a girl about 1-2 years old. Another girl, about a year old, died at a hospital, Winter said.
An investigator told reporters at the scene the victims are believed to be a mother, father and their two children.
Their names were withheld, pending notification of relatives.
The van driver was taken to a hospital for treatment of non-life-threatening injuries, according to the sheriff's department, which reported that investigators believe the family's vehicle veered into the path of the oncoming van.
