The verdict added four Philadelphia killings to a Delaware sentence that already carried seven life terms.

PHILADELPHIA, Pa. — In Pennsylvania, Keith Gibson was convicted and sentenced in Philadelphia for four 2021 murders, including the killings of his mother and a Dunkin’ manager, after jurors heard evidence tying him to a violent spree across two states.

The June 2026 verdict moved one of Philadelphia’s most closely watched murder cases from trial to punishment. Gibson, 44, had already been serving seven life sentences plus 296 years in Delaware for two killings, an attempted murder, robberies and weapons offenses. The Philadelphia case added four first-degree murder convictions for the deaths of Roy Caban, Eric Flores, Christine Gibson and Christine Lugo.

Prosecutors said the Philadelphia crimes began Jan. 28, 2021, inside a store in the city’s Germantown neighborhood. Caban and Flores were shot and killed there, placing investigators at the start of a case that would stretch into East Falls, North Philadelphia, Elsmere and Wilmington. Less than two weeks later, Christine Gibson, 54, was killed at her job inside a community center. Authorities later said her son was responsible. Philadelphia District Attorney Larry Krasner said the case showed “a pattern of brutal violence” that left families waiting years for the full criminal process to reach court.

Lugo, 40, was killed June 5, 2021, while working as the manager on duty at a Dunkin’ on the 500 block of West Lehigh Avenue. Prosecutors said Gibson forced her to a cash register during an attempted robbery, made her hand over about $300 and shot her before running from the restaurant. The killing became one of the most public pieces of the Philadelphia case because it happened at a familiar neighborhood business during the early part of a workday. Officials said surveillance video, witness accounts and the pattern of robberies helped connect the Philadelphia crimes to violence that had also unfolded in Delaware.

The Delaware portion of the case had already ended before the Philadelphia trial began. A Wilmington jury convicted Gibson in 2023 of killing Leslie Ruiz-Basilio, 28, during a robbery at a Metro by T-Mobile store in Elsmere and of killing Ronald Wright, 42, during a street robbery in Wilmington. Delaware prosecutors also won convictions linked to the attempted murder of store clerk Belal Almansoori and other robberies over several days. In March 2024, a Delaware judge imposed seven life terms and nearly 300 additional years. Judge Ferris Wharton said at sentencing that the punishment was as much as the court could give, but “it is not enough.”

Evidence in Delaware placed a revolver at the center of the investigation. Prosecutors said ballistics linked shootings, and authorities recovered the gun near where Gibson was arrested in June 2021 after a Rite Aid robbery in Wilmington. Police said the clerk in that robbery slipped a GPS tracker into a bundle of cash, helping officers locate Gibson. When arrested, he was wearing body armor and carrying ammunition. The Delaware trial also included store surveillance from the cellphone shop where Ruiz-Basilio was killed and evidence showing her SUV was later recovered in Philadelphia near Gibson’s residence.

The Philadelphia prosecution picked up after Delaware finished its case. Gibson was brought before a Philadelphia jury in June 2026 on charges tied to Caban, Flores, Christine Gibson and Lugo. The trial lasted about a week before jurors unanimously found him guilty. The charges included four counts of first-degree murder and related robbery and weapons offenses. Prosecutors said the Pennsylvania verdict answered questions that had remained open since 2021, when city investigators were tracking separate crime scenes that later appeared to fit a wider pattern. The court then imposed four consecutive life sentences plus 76 years.

The case also renewed attention on Gibson’s release history. He had a prior Delaware manslaughter conviction from 2010 and had served about 13 years before his December 2020 release. After authorities identified him as a suspect in his mother’s killing, Delaware officials accused him of violating probation by leaving the state without permission. Probation officials first sought a longer prison term, but the matter ended with a 31-day sentence. Gibson was released again April 27, 2021. Less than three weeks later, Ruiz-Basilio was killed in Elsmere. Lugo and Wright were killed in early June.

Families of the victims sat through the Philadelphia proceedings after years of delay caused by the order of the Delaware and Pennsylvania prosecutions. Frances Rodriguez, Lugo’s daughter, said relatives wanted their family members’ lives to be heard in court, not only the details of the crimes. “I deserve to have my day in court where I get to speak on the impact that his choices made on my life, my children’s life, my family’s life,” Rodriguez said. Prosecutors said the verdict was meant to recognize each victim by name and each crime as a separate act.

The Philadelphia sentencing means Gibson now faces life terms in both states, with no known remaining murder trial tied to the 2021 spree. The case stands as a completed prosecution in Philadelphia as of July 7, 2026, following the June convictions and sentence.
