NASHUA, N.H. – William Smart, who was devastated by his son’s murder in New Hampshire’s notorious Pamela Smart case and strongly opposed an early prison release for the gunman, has died at 68.

The Farwell Funeral Home in Nashua confirmed that Smart died Wednesday of pancreatic cancer at his Nashua home.

In 1990, Pamela Smart found her husband, Gregory Smart, shot to death in their condominium. Police arrested three teenagers and charged Pamela Smart, a media coordinator at their school, as an accomplice.

William Smart called her a “cold-blooded murderer” at her sentencing. He later opposed an early release for gunman William Flynn

Flynn said he killed Gregory Smart after Pamela Smart seduced him. Pamela Smart, serving a life sentence, maintains she had nothing to do with the murder.
