A 31-year-old San Diego woman was arrested on suspicion of drunk driving and drug possession after a car crash in which one of her children was killed and two others seriously injured, according to El Cajon police.
Brandy Teague was driving a 2010 Hyundai Accent that crashed into a telephone pole Saturday night in downtown El Cajon, police said.
Teague "may have fallen asleep behind the wheel before the collision occurred" about 9:40 p.m., police said.
Teague was taken to a local hospital after complaining of pain, police said. Her three children were taken to Rady Children's Hospital where the 3-year-old girl was pronounced dead.
The other two children - boys, ages 10 and 2 - remain at the hospital with serious injuries that weren't life-threatening, police said.
Teague was arrested and remains in jail on charges of gross vehicular manslaughter, felony child endangerment, drunk driving and possession of drugs, according to jail records.
