A man was seriously injured Friday morning after a shooting in Kalamazoo.

The Kalamazoo Department of Public Safety says that they were called around 2am Friday to the 700 block of Howard St. after shots were fired; no victims were found at the scene, but officers did find evidence of a shooting.

A short time after, a 33-year-old man arrived at the hospital with a gunshot wound, and he was listed in serious condition. The KDPS says he wasn’t able to provide information about the shooting.

Authorities don’t have any possible suspects identified, and they ask those who have clues to get in contact with them. The KDPS can be contacted directly, or an anonymous tip can be left by contacting Silent Observer.
