UPDATE: 12:10 p.m. The Virginian-Pilot cites "two close friends" - Eddie Greene and W. Ray White - as confirming Griffith's death. AP says Sheriff Doughtie confirmed the news, in a statement from the family, saying, "Mr. Griffith passed away this morning at his home peacefully and has been laid to rest on his beloved Roanoke Island."

Griffith, who was born in Mount Airy, N.C., was launched to fame as Sheriff Andy Taylor in The Andy Griffith Show for CBS from 1960-1968. On the show, Ron Howard played his son, Opie. He starred on other shows and in films, but found his greatest success again with legal drama Matlock, from 1986 to 1995. He played the title character, Ben Matlock.

In 2000, Griffith underwent quadruple heart-bypass surgery and in 2007 had hip surgery after a fall.

Griffith and his first wife, Barbara Bray Edwards, married in 1949. They were divorced in 1972 and she got custody of their daughter, Dixie ,and he got custody of son Sam, who died in 1996 after years of alcoholism. His second marriage, to Greek actress Solica Cassuto, lasted eight years, from 1973 to 1981.

He and Cindi Knight were married on April 12, 1983, when she was 27 and he was 56. A private man, he told the Virginian-Pilot in 2008 in a lengthy profile by Mal Vincent that he's friendly and outgoing to a point, but has been known to turn down requests for autographs. "When my wife, Cindi, and I go somewhere and we don't want to be recognized. She says, 'Don't talk.' "
