MANCHESTER - Fred Kfoury Jr., president of Central Paper Products and a well-known civic and community leader, has died at the age of 70.

Kfoury died Tuesday night in Florida, where he was vacationing, according to his son, Matt. The family believes it may have been a heart attack, but the official cause of death remained unclear.

Kfoury took over the business that his father founded in 1948. It remained in the family and expanded in an era when many independent businesses couldn't keep up with national chains.

Kfoury was honored as Citizen of the Year by the Greater Manchester Chamber of Commerce in 1998.

He was also well-known for his philanthropic activities and devotion to the University of New Hampshire, his alma mater. UNH awarded him in 2004 with its Alumni Meritorious Service Award.
