(CNN) — A man accused of shooting and killing an 18-year-old woman in a case of road rage is being held without bail on murder charges after turning himself in Sunday morning, authorities said.
David Desper, 28, faces multiple charges, including first-degree murder and reckless endangerment, Chester County District Attorney Tom Hogan said.
CNN affiliate TV station WPVI tweeted a photo of Desper released by police.
Police said he shot Bianca Nikol Roberson after he became angry as their vehicles were merging on the same lane of a highway Wednesday evening in West Goshen, Pennsylvania, just west of Philadelphia.
“They jockeyed for position and he wasn’t happy, so he pulled out a gun and shot Bianca in the head, killing her instantly,” Hogan said.
Roberson’s car drifted off and struck a tree, while the suspect’s vehicle, a red pickup truck, “took off like a bat out of hell,” Hogan said.
Roberson was killed by a single round from a 40-caliber Smith & Wesson semi-automatic handgun, Hogan said.
Police found the gun in Desper’s bedroom. He had bought in legally in November 2015 and had a permit for it, Hogan said.
He called the killing a “savage, senseless and brutal act.”
Police used video footage from surveillance cameras to identify the truck and its owner. They urged the shooter to turn himself in over recent days.
Desper did so through his attorney about 2 a.m. Sunday, Hogan said.
Roberson recently graduated high school and had been shopping for new college clothes with her mother and grandmother before she was killed, family members said. They said she had planned to attend Jacksonville University in just a few weeks.
