An autopsy has confirmed that a Chicago man was killed by at least one of his two pet pit bulls.

Charles Hagerman, 44, was found dead in his Englewood home by his wife around 8:15 p.m. Wednesday, CBS Chicago reports. Hagerman had visible bite marks and injuries, and the couple's pit bulls were hovering nearby.

One of the two dogs was biting Hagerman's neck when his wife first entered the home on the 5600 block of South Racine Avenue, according to the Chicago Tribune. The woman ran outside and called police on her cell phone, who summoned animal control personnel.

Authorities originally suspected that Hagerman was already dead when the dogs found him, according to the Associated Press.

But an autopsy Thursday confirmed that Hagerman's cause of death was multiple injuries from a dog attack, including a fatal neck injury, NBC Chicago reports. The death was ruled accidental, according to the medical examiner's office.

The city's Animal Care and Control office has removed the dogs from the home.
