See No Evil is investigating the murder of teenager Bianca Roberson, who was killed on a Pennslyvania highway by David Desper in a road rage incident in the West Goshen Township.

Bianca was an 18-year-old high school graduate from West Chester, PA, preparing to go to Jacksonville University in Florida when a chance encounter with Desper led to him pulling out a firearm and shooting her dead on the highway.

On June 28, 2017, Bianca was driving home after shopping when the two-lane highway she was traveling along began to merge into a single lane. Bianca and Desper had already started jockeying for position on the road.

Witnesses later told the cops that Bianca’s Chevrolet Malibu and Desper’s Chevrolet Silverado fought for space on the highway, with each vehicle passing the other numerous times.

However, as the lanes merged, Desper, while in the left lane, grabbed his .40 caliber Smith & Wesson semi-automatic handgun from the driver’s compartment and fired out his passenger window at Bianca. She was hit in the head and fatally wounded, leaving her car to crash off the road and into a ditch. The incident was partially caught on a surveillance camera.

At first, the investigators assumed Bianca’s death was the result of a horrific traffic accident; however, on closer inspection, they learned the teenager had been hit with a bullet.

In the meantime, Desper had fled the scene without stopping or calling for assistance. He left his pickup truck at a friend’s house and ran to another friend in Delaware. The killer then spent the next few days playing mini-golf and eating pancakes. He eventually turned himself in to the authorities.

Desper pleaded guilty to third-degree murder and was sentenced to spend between 20 and 40 years behind bars. He will be eligible for parole in 2038.

At the sentencing, Bianca’s father, Rodney Roberson, asked Desper: “Why in God’s name did you shoot my daughter? Because she was young? Because she was black? Because she was a girl? Because you wanted to go first on the road? Because you had a bad day?”

Desper apologized for the killing and said he “would do anything to take it back.”
