A suspected serial killer charged in the fatal shooting of a Philadelphia Dunkin’ store manager has been arrested in the murder of his mother, prosecutors said.
Keith Gibson, 39, will face murder charges in connection with the February murder of his mother Christine Gibson, the Philadelphia District Attorney’s Office announced Wednesday.
When his mother’s body was found at her workplace in Philly, Gibson was on parole after serving time in prison for a previous murder in Delaware, NBC Philadelphia reported.
At that time the police investigated her in the case of her mother’s death, eventually taking her into custody as the woman’s neighbors had seen her in the city violating her parole.
“At the time, we couldn’t link him to the murder,” Philadelphia Chief Inspector Frank Vanor told reporters.
But after further investigation and forensic testing in the case, prosecutors were able to file charges against Gibson on Wednesday, News station WPVI reported.
Police said they believe Gibson is linked to a series of other murders, including the fatal shooting of Dunkin’ manager Christine Lugo, 40, on June 5 in Kensington.
Police said Gibson allegedly took $300 and shot the mother of two children in the head at around 5.30 a.m.
In a separate incident in Wilmington, Del., he was arrested in connection with the murder after he allegedly shot a Right Aid cashier with a pistol, police said.
Gibson is also being investigated in the murder of a MetroPCS cellphone store manager in Elsmere in May, news station NBC10 reported.
The outlet reported that it is also interested in the deaths of two people at a North Philadelphia store in January, as well as the fatal street robbery of a man in Delaware.
