HARRIS COUNTY, TEXAS — A 14-year-old driver has been charged with murder for allegedly killing a woman after he ran a red light while throwing eggs at other cars, police in Texas said Wednesday.

The underage driver and two teen passengers were in an SUV Tuesday afternoon when another car began chasing them, the Harris County Sheriff’s Office said.

“The 14-year-old & his two teen passengers were reportedly throwing eggs at other cars just prior to the crash,” Sheriff Ed Gonzalez tweeted.

According to the sheriff’s office, the driver of the car that chased the teens allegedly showed them a semi-automatic handgun. The teens blew through the light during the chase and slammed into a pickup truck, police said.

Paramedics found Silvia Zavala, 45, dead on the scene, the sheriff’s office said.

Gonzalez called Zavala “totally innocent.” It “seems she had just gone shopping based on some debris strewn at scene,” he tweeted.
