Grand Rapids Police continue to investigate the death of businessman John Dahlinger, 56.
He was killed in his home on the Northeast side of Grand Rapids more than a week ago.
Although there are no arrests, police say that detectives were working on the case throughout the weekend and are “making progress”.
Investigators said Dahlinger’s girlfriend came home to find him dead in the home they shared. She then called 911.
Neighbors said Dahlinger and girlfriend Melanie Yanchuck lived at their home on Krislin Drive for a number of years.
Autopsy results revealed that Dahlinger was shot in the head, assaulted and suffered a heart attack before he died.
Neighbors said it appeared he was brutally beaten, and there was no sign of a break-in.
“Melanie was overcome with grief,” said Marty Staal, friend and Neighbor. “It’s shocking, shocking to the neighborhood.”
