The Daily Journal of Vineland reports Cumberland County prosecutors are investigating whether homicide or another crime was committed in the case.
Twenty-seven-year-old Michael Burris fell and hit his head in his Millville home on July 31.
Responders said in a report they restrained him because he was combative.
An autopsy found the manner of death was homicide.
Three members of the Millville Rescue Squad and two paramedics from Underwood Memorial Hospital received the suspensions last week from the state Office of Emergency Medical Services.
