PHILADELPHIA (KYW Newsradio) — The accused mastermind of the execution-style murders of four people in a West Philadelphia basement more than a year ago pleaded guilty on Tuesday.

Jahlil Porter is accused of fatally shooting two sisters and two stepbrothers in the heads. He pleaded guilty to four counts of third-degree murder, as well as robbery and weapons offenses.

"One of the more horrific killings in this city’s history, obviously, a tragedy on top of a tragedy given that very young people were involved, including a 17-year-old and a 20-year-old," said Anthony Voci, homicide supervisor for the district attorney's office.

The young victims were sisters Yaleah Hall and Tiyaniah Hopkins.

Voci says victims Akeem Mattox and Maurice Taylor-Williams found drugs in a home they were renovating along Malcolm Street and set up a drug sale with Robert Long. On that November 2018 day, Long, Porter and Keith Garner went to the home. 

Voci says that's when Porter decided to rob them.

"He was the mastermind of the robbery. He is also the individual that shot and killed all four of the victims. The only person who shot and killed all four of the victims," Voci said. 

Long pleaded guilty earlier this month to the same charges. Both he and Porter are set to be sentenced in March, facing decades in prison. Garner’s trial is still looming.

"He has not indicated or expressed any willingness to plead at this time, and his trial date is scheduled for the first week of April," Voci said.
