Authorities say that a road rage altercation preceded the fatal punching of Baltimore County man in Southeast Baltimore earlier this month and have charged a Baltimore teen in his death.

Jayden Simpson, 18, is charged with involuntary manslaughter in the death of John Hasty, 61, who died a day after the encounter, according to charging documents and Baltimore Police. The Office of the Chief Medical Examiner ruled Hasty’s death a homicide caused by blunt force trauma.

“I don’t care what he did up to this point,” John Hasty’s brother, Toby Hasty said, in an interview with The Baltimore Sun. “Nobody deserves that.”

Simpson voluntarily surrendered himself to police, according to charging documents. His attorney did not respond to multiple requests for comment.

The State’s Attorney Office has found no evidence to establish that Simpson intended to kill or cause serious harm to Hasty, according to charging documents.

According to charging documents, while driving south on Dundalk Avenue on June 4, Hasty “exchanged words,” with people in another car. A witness told police that they heard Hasty tell people in the other car to follow him into the parking lot of nearby gas station at the corner of Holabird and Dundalk avenues, charging documents say.

At the gas station in Southeast Baltimore’s Broening Manor neighborhood, near Dundalk and the Baltimore County line, three people approached Hasty, including Simpson, police say.

Simpson is accused of punching Hasty in the face once, causing Hasty to fall to the ground. The 18-year-old then, according to charging documents, “stood over Mr. Hasty and spat on him”.

“I don’t see how anybody can forgive that,” Toby Hasty, the brother, said.

In a surveillance video acquired by WBAL-TV, Hasty is shown to not make any effort to defend himself before he is punched.

Police accuse Simpson of fleeing the scene with the two other people in the car. A motion from Simpson’s attorney identified Simpson’s girlfriend and her mom as the people Hasty argued with after a “traffic incident”.

Hasty was unconscious when an officer arrived on the scene, and his mouth and ear were bleeding, according to charging documents. He was transported to Johns Hopkins Bayview Medical Center, where he died.

According to Toby Hasty, John Hasty was a retired mailman and outdoorsman who loved crabbing, fishing, traveling and selling items at flea markets. He was a longtime Rosedale resident but recently lived in Dundalk to care for their ailing mother .

“He was loyal,” Toby Hasty said.
