Police are seeking a man they say fled the scene of a head-on collision Saturday in Mountain View that injured a young mother, tossing her through a car window.

An arrest warrant for Walter Campbell, 45, has been issued, said Anchorage Police Department spokesman Lt. Dave Parker.

Campbell is described as a 6-foot-1-inch African-American male with black hair and brown eyes who weighs 215 pounds.

The incident happened around 3:30 p.m. on Commercial Drive when an eastbound white Chevrolet Tahoe, which police say was driven by Campbell, went into the westbound lane toward a purple two-door Honda driven by Peter Her, 19, in which a woman and her baby were passengers.

The Tahoe and the Honda hit head-on, which caused the Honda to spin into a building.

Police say Campbell fled on foot.

The woman in the passenger seat, 19-year-old Manevan Xiong, was thrown out of an open window of the car and went to the hospital in critical condition, police said.

The driver was treated and released from the hospital the same day.

Xiong was released from Alaska Regional Hospital on Wednesday, a hospital representative said.

A 3-month-old infant in the back seat, Jordan Her, was uninjured, which police attributed to the proper use of a car seat.
