Montrose, May 14. Robbery and Murder! We are informed that the lifeless body of Oliver Harper, son of Judge Harper, of Windsor, Broome County, N. Y. was picked up in the road, in Harmony Township, in this county on the evening of Tuesday last. The deceased has been down the river with lumber, and was on his return home, with money to a considerable amount, as is supposed, when this horrid act was committed. It is evident that the villain was fully determined upon accomplishing his hellish design, as two bullets were discharged at the unfortunate victim, one of which entered his head, the other passed through his hat just above it. It is to be hoped that prompt measures will be taken to detect the perpetrator of this attrocious deed. Republican.
