PHOENIX -- A pregnant woman who was involved in a brutal car wreck Thursday evening has died. Her baby, however, survived.
It happened at about 7 p.m. near 39th and Northern avenues.
Karlisha Randolph, 24, was trapped in her vehicle for a time. Rescue crews had to cut her free.
She, along with four other people, was taken to a local hospital.
While Randolph later died, doctors were able to save her full-term baby boy. That infant is in critical condition.
According to police, it started when the 21-year-old driver of a red 1997 Volvo made a right turn from southbound 35th avenue to westbound Dunlap. That Volvo turned in front of a city bus that was also southbound on 35th Avenue.
Nobody on the bus was hurt, but the driver of the Volvo fled the scene, turning on to southbound 39th Avenue. The driver then blew through the red at Northern Avenue, slammed into a 2001 Suzuki Vitara.
The impact caused the Vitara to roll. It eventually came to a rest on its side against the pole of a traffic signal. The Volvo ended up plowing into a wall.
The other victims -- a 2-year-old and a 7-year-old who were in the Vitara, the 43-year-old driver of the Vitara and driver of the Volvo -- all suffered non-life-threatening injuries.
According to Sgt. Tommy Thompson of the Phoenix Police Department, investigators believe the driver of the Volvo was impaired. He will face a variety of charges as soon as he is released from the hospital.
The already complex investigation was complicated further when another allegedly impaired driver drove past the traffic barriers and through the crash scene.
A 45-year-old man was behind the wheel of a 1995 Cadillac that hit two vehicles belonging to investigators who were working the scene. One of those vehicles was totaled. The driver was injured and taken to a local hospital.
Like the driver of the Volvo, he also will face charges when doctors release him.
