GREAT FALLS (AP) -- After years of investigation and a weeklong trial, a jury took four hours to find Wilfred ''Bill'' Morrisey guilty of killing 9-year-old Dolana Clark in 1988.
''All this time, I knew he was guilty,'' Dolana's half sister Janine Wall said after the verdict was announced Thursday night.
Clark was last seen riding her bike on Aug. 2, 1988. A hunter found her skull, with a bullet hole in it, in the Little Belt Mountains in the fall of 1989.
Morrisey, 65, a Clark family friend, was interviewed after Dolana's disappearance. Friends said Morrisey's demeanor changed dramatically, he severed ties with the Clark family and moved to Illinois a few months later.
Police reopened the case in 2002.
Cascade County Attorney Brant Light said the trial was ''about a man whose actions and words scream loudly, and if you listen they'll say he's guilty.''
Morrisey's attorney, Greg Jackson, argued that there was no physical evidence tying his client to the crime, and said the inconsistencies in Morrisey's stories were because of the time that lapsed since Dolana disappeared.
Morrisey's sentencing is scheduled for Dec. 20.
