(AP) - Authorities outside Detroit are ruling the death of a man who fought with a teenager at a Hank Williams Junior concert as a homicide.

Officials say they hope to wrap up their investigation by the end of this week into the death of 55-year-old Robert Kobe. Authorities say a 15-year-old boy shoved Kobe during a concert last weekend. Kobe hit his head on the concrete and died. The teen has been released from custody pending the conclusion of the investigation.

Kobe's son, Cory Kobe, tells the Detroit Free Press the death appears to be accidental.
