CROWN POINT | The Lake County coroner's office has ruled the Fourth of July death of a Chicago teen a homicide.
An autopsy completed Thursday morning found Kevin Kennelly, 17, died of blunt force trauma to the head, a spokesman for the coroner's office said.
Kennelly, of the 9900 block of South Damen Avenue, died Wednesday at Franciscan St. Anthony Health in Crown Point after being found unconscious Monday during a holiday celebration in Long Beach.
Kennelly is believed to have been assaulted while trying to break up a fight on the beach.
James K. Malecek, 19, of Chicago and Long Beach, was arrested and taken to LaPorte County Jail, police said.
Malecek is charged with aggravated battery, involuntary battery and battery in connection with the incident.
He bonded out of jail on a $25,000 cash bond Thursday afternoon, LaPorte County sheriff's Maj. Gary Broling said.
Police declined to say Thursday whether they will seek additional charges in the wake of the homicide ruling.
"It is an ongoing investigation," a police spokesman said.
