John Graziano was a passenger when Nick Bollea, Hulk Hogan's son, had his car accident last year. Graziano was nearly killed and sustained permanent injuries.
Clearwater, Fla. police are investigating the phone calls, although police spokesman Doug Matthews did not reveal the family member behind the threats. He also declined to name the Hogan party on the receiving end of the calls.
Morris Weinberg, an attorney for the Hogans, has confirmed that the police have listened to the threatening messages left on his clients' voicemail, although he did not reveal the content of said messages.
"Does the family take it seriously? Yes, they do," Weinberg said.
At this time, information is still pending. No charges have been filed and no arrests have been made thus far.
