The suspect in the Pennsylvania road rage killing, which took the life of a high school graduate named Bianca Roberson, turned himself in on Sunday days after the incident.

Police tried to hunt down the 28-year-old suspect identified as David Desper for four days. The search even expanded to three states. Per police reports, Desper surrendered at around 2 a.m. on Sunday. He now faces charges of first-degree and third-degree murder in the death of Roberson. He also faces possession of an instrument of crime and reckless endangering charges. The suspect is not allowed to post bail.

Police: killing is not race-related

Roberson is white and the victim was black.

It was suggested that the killing of Roberson might have been race-related or was a hate crime but police said there was no indication that that is the case. They only have proof that the killing was a result of a Road Rage.

What police found related to the shooting

The red pickup truck of Desper was found after the killing. A 40-caliber semi-automatic handgun was also found at the bedroom of the suspect and officials believed it was the weapon he used in the shooting. Police did not say if the vehicle was abandoned or if Desper drove the vehicle when he surrendered himself. Desper purchased the gun in November of 2015 and had a permit to own one, New York Daily News reported.

Suspect got angry over their vehicles merging on the same lane

Police are saying that the main reason why Desper shot Roberson was because he got mad that their vehicles were merging on the same lane. Desper did not want Roberson merging into traffic so he shot at her.
