A third person is now in custody in connection with last week's stabbing death of a barber in Pittsfield.
The Berkshire County DA's office says Jason Sefton of Pittsfield surrendered to police early Monday.
He pleaded not guilty to a murder charge and will appear back in court next month.
William Catalano was found with multiple injuries including stab wounds in the 200 block of Robbins Avenue.
He was taken to Berkshire Medical Center where he later died.
Bruce Romano and Anthony Boone were arrested last week for Catalano's murder and are being held without bail.
