Walter Palmer climbed one flight of stairs to the second floor of an apartment building at 16 Millbury Street in Worcester’s Green Island Neighborhood.

It's Saturday evening, August 5,1989, Palmer was surprising his friend John Riley.

The door to John’s studio apartment was locked, so Palmer used his spare key.

When he opened the apartment door, Palmer stood there in shock.

John Riley sat lifeless in his chair. A pool of blood was at John’s feet.

John was murdered. He had been stabbed 29 times
