The 28-year-old turned himself in to police on Monday. He is being held without bail due to his criminal history, which includes crimes in Massachusetts, Connecticut and North Carolina. Cardona faces the possibility of life behind bars.
He was told to have no contact with a witness to the crime and any family members of his alleged victim, 38-year-old Patrick Mullinnex. Mullinnex was found shot to death in a Pleasant Street apartment on August 3.
In the affidavit, Cardona and a witness told police that the two may have been involved in an alleged drug sale with the victim.
