Alleged 'serial killer' taken into custody after shooting and killing Dunkin’ manager

An alleged "serial killer" accused of murdering a Dunkin' manager in Philadelphia has been caught, police said.

Keith Gibson was arrested in Delaware on June 8 after Philadelphia police offered a $20,000 reward for information leading to his arrest, according to multiple media outlets.

Philadelphia homicide detectives said that Gibson has been labeled a “serial killer,” according to CBS Philly.

Gibson is the suspected gunman in the fatal shooting and robbery of Christina Lugo, 41, a manager at a Philadelphia Dunkin' over the weekend. Just before 5:30 a.m. on June 5, police say Gibson fatally shot Lugo during a robbery.

Coworkers told CBS Philly Lugo was a mother of two with a “kind heart and smile.”

After the Dunkin’ shooting, Gibson allegedly shot and critically wounded a 19-year-old in Wilmington, Delaware, and pistol-whipped a female worker at a Rite Aid in New Castle, Delaware, according to CBS Philly.

Police say Gibson killed his mother on Feb. 8 and killed a worker at a T-Mobile store in Elsmere, Delaware, on May 15, CBS Philly reported.

In 2008, he was convicted and served time in prison for homicide and robbery in Delaware, CBS Philly reported.

Gibson was wearing a bulletproof vest and was armed with a knife and loaded gun when he was arrested, according to CBS Philly.

Police say they found a revolver that is believed to be connected to many of the shootings. So far, Gibson has been charged with first-degree robbery and is being held in Delaware.
