(PHILADELPHIA) Philadelphia police arrested a man they believe to be a serial killer in connection to the murder of a Dunkin Donuts manager, according to CBS 3.
Keith Gibson was taken into custody by police on Tuesday. Gibson is accused of shooting Dunkin Donuts manager Christine Lugo over the weekend as she opened up her location on the 500 block of West Lehigh Avenue.
Authorities said Gibson also shot a 19-year-old in Wilmington and pistol-whipped a female worker at a Rite Aid in New Castle after he murdered Lugo.
Gibson is also accused of killing his own mother in February and a T-Mobile store employee in May.
He was convicted for committing a homicide in 2008 in Delaware during a commercial robbery.
The police recovered a revolver that is believed to be connected to all of the shootings.
