A prosecutor says a preliminary review indicates police were justified in fatally shooting a man suspected of killing a Pennsylvania state trooper.

Huntingdon County District Attorney David Smith said Friday he's not sure when his review of facts surrounding the killings of Trooper Landon Weaver and 32-year-old suspect Jason Robison will be complete.

State police have said Robison shot Weaver on Dec. 30 while the trooper was questioning Robison about the possible violation of a protective order.

Police have said they tracked Robison to a central Pennsylvania mobile home the next day and shot him after he made threats and didn't comply with commands.

Weaver was 23 years old and had been a trooper for about a year.
