A jury Friday found Pamela Smart guilty of masterminding the murder of her husband of less than a year so she could pursue her love affair with his teenaged killer.

Smart, 23, stood quietly but a roar went up in the packed courtroom and wild sobbing was heard as the jury of seven women and five men returned the verdict.The Rockingham County Superior Court jury deliberated about 14 hours over three days before returning their verdict on charges of being an accomplice to first-degree murder, conspiracy and witness tampering.

Judge Douglas Gray immediately sentenced her to life in prison without hope of parole.

The sensational trial attracted media attention from across the United States and abroad and held New Hampshire spellbound for weeks as viewers tuned in to the live-televised proceedings.

Gregory Smart, a 24-year-old insurance salesman, was shot to death execution-style in the hallway of the couple's Derry condominium on May 1, 1990. His wife, Pamela, discovered the body as she returned home from a meeting at Winnacunnett High School in Hampton, where she was director of media services for the school district.

She ran screaming from the home and police initially believed that the shooting was the result of a botched burglary attempt.

On June 11, three Seabrook teenagers were arrested for the murder after a friend of the teens heard them talking about the crime and went to the police. Suspicion later began to focus on Smart as authorities learned of her relationship with William Flynn, now 17, one of the arrested teenagers, and she was arrested Aug. 1.
