An 11-year-old girl died and five young teenagers were injured in a car crash in Northern California early Sunday morning when an SUV crashed into a tree, local authorities said.

The accident occurred near Stockton, California, about 85 miles east of San Francisco, when police officers rushed to the 5800 block of N. El Dorado Street because a vehicle had collided with a tree. According to Stockton police, when officers arrived at the scene, they confirmed that the victims included five girls, ages 11, 13, 14 and 15, and a 13-year-old boy. All those involved in the accident were taken to area hospitals for treatment.

However, according to Stockton police, the 11-year-old succumbed to her injuries in hospital, while the other teens were treated for what were believed to be non-life-threatening injuries.

“The 11-year-old female died at the hospital from injuries sustained in the collision. The other five were taken to area hospitals for treatment of what appeared to be non-life-threatening injuries,” Stockton police said in a Facebook post.

Details of the accident are still unclear, including who was driving the vehicle at the time. Stockton police said the investigation is ongoing.

According to the Associated Press (AP), Omer Edhah of the Stockton Police Department called the incident alarming and disturbing and told local news station ABC10 the importance of being vigilant in the community, urging parents to keep an eye on their children’s whereabouts and to keep a close eye on car keys.

“And our message to the public is: be careful where your children are, where your car keys are, who you give your keys to and be alert all around,” Edhah told ABC10.

Newsweek reached out to Stockton police via email on Monday for comment.

According to the National Highway Traffic Safety Administration (NHTSA), the number of teen car occupant deaths in 2022 totaled 2,547, a 7.2 percent decrease from 2,744 in 2021. However, car crashes remain the leading preventable cause of death among teens in the United States.

NHTSA also estimates that the total number of deaths among youth ages 13 to 19, including pedestrian and bicycle crashes, was 2,883 in 2022, an average of nearly eight deaths per day.

Sunday’s incident came less than two weeks after three people were killed and several others injured in Kansas City, Missouri, on August 13 when a teenage driver crashed a stolen car.

Kansas City Police said in a press release previously emailed to Newsweek that the incident began when a 16-year-old driver fled a police traffic stop in a stolen vehicle. The teenager, who was behind the wheel of a Kia Soul that had been reported stolen earlier this month, initially complied with police orders to stop.

As a police officer approached the vehicle, which contained seven passengers, including four children, the teenager suddenly sped away. Authorities confirmed that the officer did not pursue the fleeing vehicle.

Shortly after fleeing, the Kia, which was traveling eastbound on 35th Street “at a high rate of speed,” collided with a Chevy Tahoe. The Tahoe, which was attempting to turn left, was struck and spun around before the Soul struck a utility pole and flipped onto its roof.

According to authorities, the teenage driver and the 37-year-old passenger were pronounced dead at the scene of the accident.

A second passenger who was taken to a hospital was pronounced dead shortly after arrival. The remaining five passengers in the Kia Soul suffered serious injuries but are expected to survive.
