Joseph Spiers, 27, of Chester, Pennsylvania, was found dead of a gunshot wound to the head on the enclosed porch of William Muscolini’s house on December 24, 1987. According to reports, the shooting followed an argument. Muscolini, then 21, was found at the scene carrying a rifle, held without bail, and charged with murder.

Police say he held officers off for about 90 minutes, threatening to shoot himself before surrendering after intervention by a friend, Frank Wonderly. Muscolini was scheduled for arraignment in the Court of Common Pleas on March 7, 1988.

Does anyone have additional information about the investigation, the trial, or what led to the argument?
