PHILADELPHIA - Authorities say a woman has been arrested in the "execution style" murders of two people in Fairmount Park.
The Philadelphia Police Department on Wednesday reported that the unnamed woman surrendered to police.
It's the second arrest in the gruesome double murder that police say happened overnight on Feb. 29.
Police found the bodies of Thurston Cooper, 49, and Krystina Chambers, 38, near three shell casings on Mount Pleasant Drive.
Police arrested a man in connection to the murders days later, and recovered a car they believe is linked to the killings.
Investigators have not shared a possible motive.
