The Philadelphia verdict followed a timeline that began after a Delaware prison release in 2020.
PHILADELPHIA, Pa. — Keith Gibson’s conviction for four Philadelphia murders closed a case that began soon after his release from Delaware prison and moved through probation violations, two states and six deaths in 2021.
The June 2026 Philadelphia sentence added four life terms plus 76 years to a punishment Gibson was already serving in Delaware. Prosecutors said he killed Roy Caban, Eric Flores, his mother, Christine Gibson, and Dunkin’ manager Christine Lugo while free after earlier convictions. The case now stands as both a murder prosecution and a record of how quickly violent crimes followed prior release decisions.
Gibson’s earlier criminal history dated to Delaware. He was convicted in 2010 of manslaughter and a gun charge and received a 20-year sentence. He served about 13 years before being released in 2020 to community supervision. A later violation sent him back to custody, but he was released again in December 2020 with probation still in place. Within weeks, authorities said, he left Delaware and returned to Philadelphia. That movement became important later because officials said he did not have permission to cross state lines under the terms of supervision.
On Jan. 28, 2021, Caban and Flores were shot to death inside a Germantown store. Less than two weeks later, Christine Gibson was killed at her job in a Philadelphia community center. Police later identified her son as the suspect in her death. Delaware officials then charged him with violating probation by leaving the state. At first, probation officials sought a sentence that could have returned him to prison for years. The matter ended differently after court arguments about his plans for housing and work in Philadelphia. He received 31 days.
Gibson was released again April 27, 2021. Less than three weeks later, prosecutors said, he killed Leslie Ruiz-Basilio during a robbery at a Metro by T-Mobile store in Elsmere, Delaware. Her vehicle was stolen and later found in Philadelphia. That killing became part of the Delaware case, not the Philadelphia trial, but it filled a key gap in the overall timeline. It showed that after the short probation sentence, the alleged violence had resumed outside Pennsylvania. Delaware prosecutors later said the crime was captured on store surveillance and connected to other evidence.
The early June sequence moved quickly. On June 5, 2021, prosecutors said Gibson confronted Lugo as she worked at a Dunkin’ on West Lehigh Avenue in Philadelphia, forced her to turn over about $300 and shot her. Later that period, authorities said, he killed Ronald Wright in Wilmington and committed other robberies or assaults. The events ended June 8, 2021, when police arrested Gibson after a Wilmington Rite Aid robbery. Officials said the clerk had included a GPS tracker with cash, leading police to Gibson. Officers said he wore body armor and carried ammunition at arrest.
The supervision history became a major context point in public reporting because the killings happened after several chances for confinement or monitoring. A judge had imposed the 31-day sentence after Gibson’s probation violation, and he was back on the street in late April 2021. Prosecutors in later trials focused on what happened after that date, not on the release decision itself. Still, the timing framed the case for families and communities. Ruiz-Basilio died May 15. Lugo and Wright died in early June. Other surviving victims were attacked during the same short span.
Delaware tried Gibson first. In 2023, jurors convicted him in the murders of Ruiz-Basilio and Wright, the attempted murder of Almansoori, robberies, assault and weapons offenses. Prosecutors used surveillance video, ballistics, recovered ammunition, stolen property and witness testimony. Defense lawyers in Delaware challenged the strength of the evidence and pointed to what they said was a lack of direct forensic proof at some scenes. Jurors convicted him, and in March 2024, the court sentenced him to seven life terms plus 296 years. Only after that did the Philadelphia case move forward.
The Philadelphia trial began in June 2026 and lasted about a week. Gibson was tried for the four city killings from January, February and June 2021. The jury found him guilty on all four first-degree murder counts. District Attorney Larry Krasner’s office announced the convictions and sentencing the next day, saying the case had been handled by its Homicide and Non-Fatal Shootings Unit. The Philadelphia sentence of four consecutive life terms plus 76 years meant that the Pennsylvania court formally punished the killings of Caban, Flores, Christine Gibson and Lugo, even though Gibson already faced life imprisonment in Delaware.
Families attended the proceedings because the Philadelphia verdict remained important beyond the length of any added sentence. Lugo’s daughter, Frances Rodriguez, said she wanted the chance to speak about the impact on her life, her children and her family. The same issue applied to the other victims’ families, who had waited while Delaware completed its trial and sentencing first. Prosecutors said the Philadelphia case recognized that each death required its own verdict. The release timeline explained how the case unfolded, but the verdicts answered the legal questions placed before jurors.
Gibson is serving life sentences in both Delaware and Pennsylvania. The remaining public focus is on the record left by the cases, including the probation timeline, the court decisions and the victims whose deaths were separated by months and miles.
