KEY POINTS:
Three people convicted of killing an Upper Hutt great-grandmother by firebombing her house were jailed today.
Carol May Clayton, 57, was found guilty of murdering Joan Betti, 71, on September 3, 2005.
Richard Steven Pearce, 21 and Nicholas Andrew Edgarton, 19 were found guilty of Mrs Betti's manslaughter.
The trio admitted started the fire in which Mrs Betti died in September 2005.
Clayton was also found guilty of attempting to kill Mrs Betti's daughter and granddaughter Judith Betti and Latisha Owens, both of whom she suspected of having sexual relationships with her boyfriend, David Betti.
The Crown said Clayton orchestrated the arson attack on Mrs Betti's home out of jealousy, and her co-defendants, who were boarders at her house, threw molotov cocktails in the house.
Mrs Betti died from smoke inhalation.
Clayton was sentenced to life imprisonment with a minimum non-parole period of 13 years.
Pearce was jailed for seven years and Edgarton six years.
