The 40-year-old man fell about three stories to the ground.
The incident happened early Friday morning at Nickels Arcade, a covered shopping center located just outside the University of Michigan.
Police say the 31-year-old man jumped from the 1,000 foot tower Wednesday evening.
“He was standing right in front of me and then all of a sudden he was just gone,” the man’s girlfriend said.
Authorities say a 24-year-old man was fatally injured when he fell 70 feet while camping near a waterfall in the Upper Peninsula’s Pictured Rocks National Lakeshore.
