PHILADELPHIA (AP) — Police say they've arrested two men in a crash that killed a mother and three children as they crossed a Philadelphia highway notorious for pedestrian deaths.

A police spokeswoman said Wednesday night the men were being charged with four counts each of third-degree murder, homicide by vehicle and involuntary manslaughter.

The men are accused in a Tuesday night crash that killed 28-year-old Samara Selena Banks and her 4-year-old, 1-year-old and 7-month-old sons. Her 5-year-old surviving child is in stable condition with bumps and bruises.

Police say a witness reported drag racing may have been involved.

Police say the suspects also will face charges of recklessly endangering another person, aggravated assault, simple assault and aggravated assault by vehicle.
