The others were related to other criminal activity.
Three of the four that occurred in Hagerstown had similarities. In each case, a man from another state was shot in the head at close range. Those 1997 homicides were:
Michael Eric Mackason, shot to death March 23 on West North Street. Two arrests have been made.
Eric "Supreme" Williams, shot to death July 7 on Lanvale Street. No arrests have been made.
Christopher Young, shot to death on Bethel Street Nov. 23. One arrest has been made.
Authorities believe drugs played a role in all three shootings.
The other city case was the robbery and slaying of Matthew Hovis behind the Alexander House Aug. 25. Two arrests were made.
The other slaying in the county also occurred during an incident that began Aug. 20 in which Darrius Fetterhoff was robbed and pushed over a cliff. He died of his injuries Aug. 28.
The charges against the man first implicated in that slaying were later dropped when the state's chief witness disappeared. The investigation is still open.
