Freddie Mac, 57, who lives in Texas, USA, has not been heard since April 19, according to the viral news on the Internet.
Family members told the presence of 18 aggressive dogs on the property prevented them from checking the Mack house.
Investigators on May 10 registered Mack as a missing person.
Investigators returned to the house on May 15 and found a small piece of bone.
Detectives captured the dogs for a thorough search on May 19. They found animal faeces containing bone pieces, fragments of cloth and human hair.
After the forensic and DNA test, they’ve cleared that the aggressive dogs consumed Mack.
“During our investigation, it was found that Freddie suffered from serious medical conditions so we will never know if the dogs killed Mr Mack or consumed him after he died from a medical condition,” Johnson County Sheriff Adam King declared.
