GRAND RAPIDS, Mich. (WZZM) -- Police have released more information about the arrests in the murder of 23-year-old Joel Battaglia.
He was beaten to death in 1990 as he walked home from a nearby bar.
Authorities say recent billboards focusing on unsolved murders in Grand Rapids raised awareness about the case and helped with the investigation.
"On the billboards, we ask people to call Silent Observer -- and people do," said Silent Observer executive director Chris Cameron. "People call us about those crimes, but they also call us about other crimes in their neighborhood, so it's been a really good thing to do."
WZZM 13's parent company helped fund the billboard campaign through a $5,000 grant from the Gannett Foundation.
