HARRISON, N.J. (CBSNewYork/AP) — Funeral services will be held Monday for the longtime mayor of Harrison who died after collapsing in his Town Hall office.

Mayor Raymond McDonough, 65, apparently suffered a massive heart attack Wednesday afternoon.

Officials have said McDonough collapsed shortly after returning from lunch. He was found by an attorney who had an appointment with him.

The funeral will be held at Holy Cross Church at 10 a.m. Monday, The Newark Star-Ledger reported. Public viewings are scheduled Sunday from 1 to 4 p.m. and again from 6 to 9 p.m. at Mulligan Funeral Home, according to the newspaper.

McDonough, a lifelong Harrison resident, had served on the Town Council for 17 years before becoming mayor in 1995. He was credited with spearheading the redevelopment of the 1.2-square-mile Hudson County town on the Passaic River, which has about 14,000 residents.

McDonough was among a number of Democratic officials statewide who supported Republican Gov. Chris Christie for re-election last year.
