St. Louis detectives investigate woman's death on Interstate 44

ST. LOUIS -- A woman killed by a tractor-trailer after she crawled into traffic on Interstate 44 to escape an attacker was identified this weekend as Janine Lifritz, 45, of House Springs, Mo.

Detectives continued to look Sunday for the driver of the tractor-trailer and the man who was allegedly beating Lifritz, police said.

Witnesses told police a man knocked Lifritz to the ground and was kicking her in the head. She crawled on the pavement to get away and moved from the shoulder to a driving lane, where she was struck by the tractor-trailer. She died instantly, police said.

The truck driver didn't stop, and it is unclear if the driver knew Lifritz had been hit. Her attacker ran away from the scene before police arrived.
