On the night of June 9, 2023, police responded to a report of a shooting in the 7100 block of Jackson Street, in the Tacony section of the city, and found Dooner on the street with multiple gunshot wounds to his torso, police said.

He was rushed to Jefferson Torresdale Hospital and pronounced dead shortly afterward.

Santiago had recently ended a relationship with Dooner’s daughter, and he and the daughter, whom police did not identify, had an argument inside Dooner’s home, police said.

During the argument, Santiago threatened the daughter and others in the house before leaving, police said.

Santiago returned to the house soon afterward and shot Dooner before fleeing in a white Jeep, police said.

Investigators recently learned that Santiago was staying at the Hunting Park house and took him into custody on Wednesday.
