Police tape has been set up across various spots around the walking trail.

A series of mysterious deaths occurred over the past year along the Lansing River Trail, a famous landmark in Lansing, the capital of the U.S. state of Michigan.

Five homeless men ranging in their 20s to 70s were found dead with stab wounds or brutal assault injuries in secluded areas such as under river bridges.

As crimes targeting only socially vulnerable people in similar situations continued on the peaceful downtown walking trail, police went on high alert.

Police held an emergency briefing and officially announced that they are investigating the possibility that these incidents are serial murders committed by the same culprit.

Police have arrested and indicted a prime suspect in connection with the murder of a 22-year-old young man that occurred last August.

However, it has not yet been clearly revealed whether the captured suspect committed the remaining four serial crimes, or if there is a copycat crime or another accomplice.

As Michigan State University and the State Capitol are located near the walking trail, the anxiety of students and residents has reached its peak.

Local authorities have completely restricted access to the walking trail at night, significantly reinforced police patrols, and initiated emergency security measures for vulnerable homeless shelters.
