HESPERIA A citizen helped authorities catch a hit-and-run driver who caused a fatal crash Monday which killed two women and injured a 7-year-old boy, San Bernardino County Sheriff's Hesperia station officials said.


"We've had a lot more citizens getting involved and in this case it really helped in detaining this driver," Lt. Mike Stansell with the Hesperia station said.


A Ford sport utility vehicle was traveling on Highway 395 near Smoke Tree Road at about 2 p.m. when it was hit by a blue pickup truck, causing the black SUV to crash into a pole, killing the female driver and passenger, said Sgt. Ken Lutz with the Hesperia Station. The child suffered minor to moderate injuries and was flown to Loma Linda University Medical Center.


According to initial reports, one of the women killed was the child's mother.


The driver of the truck then fled, according to Lutz.


A witness followed the hit-and-run driver, relaying information to authorities, but eventually lost track of the suspect. With the information provided by the good Samaritan, deputies were able to detain the driver of the truck, Stansell said. The driver's identity was not immediately released.


Officials had shut down Highway 395 between Main Street and Bear Valley Road for several hours as members of the Major Accident Investigation Team investigated the crash.


It was not immediately clear how the initial collision occurred.
