Roll of Honor
Incident
Watchman Patrick Slevin succumbed to a gunshot wound sustained three days earlier while approaching a group of men near the intersection of 10th Street and Catharine Street.
Watchman Slevin's Captain had held roll call in the area of 13th Street and Christian Street due to a suspicious fire of a horse stable and the fear there was going to be retaliation against a group of men who were causing crime in the area. After roll call, the Captain started to walk back to the city hall, believing there was going to be no retaliation. As he reached the area of 10th Street and Catharine Street he spotted a group of men near a hillside near a fenced-in area.
He was surrounded by the group of eight men who threatened him shoot him unless he turned around and left the area. Due to only being armed with his baton he left the area and met Watchman Slevin and another officer a couple of blocks away. As the three officers returned to the area multiple shots were fired from the group. Watchman Slevin was struck in the chest, and the Captain was struck twice in his leg.
Watchman Slevin was taken to his home where he succumbed to his gunshot wound three days later.
It is not known if anybody was ever captured and held officer Sleven's murder.
Watchman Sleven was survived by his wife, and two small children.
