PITTSBURGH — Two men charged with ambushing a suburban Pittsburgh cookout and killing five adults and an unborn child face a hearing to determine whether they’ll stand trial.

Cheron Shelton, 29, and Robert Thomas, 27, each face six counts of criminal homicide and other charges in the March 9 shooting in Wilkinsburg.

Allegheny County prosecutors say Thomas fired a handgun so the guests would run for cover toward a home, where they were gunned down on a porch by Shelton, who fired an assault rifle from close range.

Authorities believe they were trying to kill a cookout guest who the suspects believe killed Shelton’s friend in 2013.
