A Pennsylvania man turned himself Sunday in connection with last week's road rage slaying of a teenager there last week.
David Desper, 28, was accompanied by an attorney when he arrived to face charges in the pre-dawn hours after days of pleas from authorities for him to do that very thing.
The Delaware County man has since been charged with first-degree murder, third-degree murder, possessing an instrument of crime, and recklessly engaging others.
The charges stem from an alleged encounter he had with 18-year-old recent high school graduate Bianca Roberson.
Both parties were behind the wheel, police say, when witnesses tell cops Roberson and the driver of a red truck began "jockeying" for position where the road narrowed from two lanes into one.
At the shocking conclusion of what authorities have called a high-speed "cat and mouse game" between Roberson and the red truck's driver, the teen with plans to attend Jacksonville University in Florida this fall was fatally shot in the head.
Roberson's car then collided with the red truck, at which point her vehicle left the road and was later found in a ditch.
The red pickup truck took off "like a bat out of hell" following the incident and was seen in surveillance footage that authorities distributed far and wide with calls for tips and for the suspect to turn himself in, according to the DA.
"This is a story of a savage of senseless murder," Chester County District Attorney Tom Hogan told reporters Sunday at a police station in West Goshen, where the killing took place.
After he turned himself in, investigators say they say they found a red pickup with a dent at Desper's home, as well as the suspected murder weapon.
Hours before Desper turned himself in, a vigil was held in Roberson's memory.
