PHOENIX (3TV/CBS 5) -- Investigators say the driver who ran a red light and caused a crash that killed a mom and her two kids in Phoenix was going more than double the speed limit right before impact. Police say 33-year-old Raymond Montgomery was going 97 miles per hour three seconds before the crash at Seventh and Missouri avenues on Thursday afternoon. About a half a second before the crash, he was going more than 70 mph in the SUV he stole, detectives said.
Montgomery has been booked into jail. He has been charged with robbery, three counts of homicide, theft and multiple counts of assault.
Investigators say the three people who died -- a family -- were all in the same car. Ali Geer, 18, and Almira Geer, 16, were both pronounced dead at the scene. Their mother, 45-year-old Courtney Lonergan, died at the hospital. Ali was behind the wheel. A GoFundMe page has been set up to assist with funeral costs.
This started with a report of a stolen SUV in the area of 17th and Missouri avenues just after 3:45 p.m. Investigators said a woman was in her dark blue Cadillac SRX when Montgomery, who she knew, punched her in the face and then stole her SUV. Police say she managed to get out before he drove away.
A few minutes later, Montgomery sped through a red light at Seventh and Missouri avenues, according to police. The Cadillac collided with a white Honda Civic driven by Ali.
The force of that crash caused a chain reaction, hitting a Dodge Ram pickup truck that had a father and his 5-year-old son inside. The pickup truck was then shoved into a City of Phoenix bus. No one on the bus was hurt.
Montgomery continued east on Missouri Avenue, striking a woman in the crosswalk and another car. The pedestrian and the driver of that car suffered injuries that aren't life-threatening.
A total of five vehicles were involved in the wreck. In all, six people, including Montgomery, were hurt. Police say Montgomery may have been impaired.
