PITTSFIELD, Mass. — A 44-year-old man died Sunday after being assaulted in the apartments operated by the Pittsfield Family YMCA.

Joseph Wirtes, 44, was allegedly assaulted by Brian Signor at the apartments Sunday morning. Wirtes was transported to Berkshire Medical Center following the assault and was pronounced dead later that day.

Signor, 27, also of the YMCA's 292 North St. residence, was arraigned on Monday on a single count of aggravated assault and battery, according to the district attorney's office. He pleaded not guilty and is being held at the Berkshire County House of Correction on $50,000 cash or surety bail.

Further charges may be forthcoming, according to the DA, pending the results of an autopsy being conducted on Monday by the Office of the Chief Medical Examiner in Holyoke.
