Police say 26-year-old Michael Cogan was stabbed to death about 4:50 a.m. Monday in the 2600 building of The Greens at Pine Hill.
A 29-year-old Philadelphia man, Stefan Curry-Burkett, was arrested on Blackwood-Clementon Road near The Birches Apartments.
A Clementon police officer spotted Curry-Burkett running from The Greens at Pine Hill shortly after the stabbing was reported and detained the fleeing man.
Curry-Burkett is charged with Murder and Felony Murder.
He is scheduled to be arraigned Tuesday.
Police say Curry-Burkett broke into the victim's apartment by climbing onto a balcony and entering through a sliding glass door.
In the apartment, police say he assaulted Cogan and stabbed him repeatedly.
According to officials, Cogan was in a relationship with Curry-Burkett's estranged wife and they believe he was targeted by the suspect.
Early reports indicated this to be a double stabbing, but that is no longer the case.
