LISBON — A 23-year-old Augusta man serving a life sentence for a brutal machete attack on a Maine family is appealing his conviction and sentence.

Daniel Fortune was convicted of attacking a Pittston father and daughter during a late-night home invasion in May 2008 that left William Guerrette Jr. and his 10-year-old daughter near death and permanently injured.

The Maine Supreme Judicial Court will hear arguments today from Fortune’s attorney at a hearing held at Lisbon High School.

Fortune’s attorney is arguing that the evidence did not support the jury’s conclusion that premeditation and extreme cruelty were proven on the aggravated attempted murder count. He also says a life sentence is too severe.

Fortune’s roommate and foster brother, Leo Hylton, is serving a 50-year sentence for his role in the attack.
