A 77-year-old Georgia grandfather beloved by his friends and family was allegedly murdered and then gruesomely dismembered by a neighbor, WXIA-TV reports.

Authorities this week located parts of Robert Page’s body in a cooler inside his next-door neighbor’s residence and found other body parts under tarps in the yard.

The macabre discoveries came after Page’s wife, Lula Page, reported her husband missing on November 8.

Investigators say the suspect, 25-year-old Christian Ponce Martinez, was seen on security camera footage on Page’s property the evening he went missing.

Authorities were able to track a blood trail from Page’s house to the home next door, where his remains were found. Police also located Ponce Martinez there under a couch; he had been renting a room in the home for the past three months after entering the country from Mexico, the television station reports.

Ponce Martinez is reportedly not cooperating with police. Officials are working with the federal government to assess whether he is in the country legally, according to Maj. Craig Hammer of the Clayton County Police Department.

It’s not yet clear what exactly motivated the killing, but investigators believe there may have been some sort of argument between the two men.

Hammer said Page was a “good man” during a news conference on Friday. Page and his wife were married for 49 years and had two children and two grandchildren.

“According to his wife, he never left his residence, he always stayed at home . . . he got along with other residents and was always a good gentleman,” Hammer said.

Neighbors on Friday stopped by the Page home to offer support for the family. Friend Nancy Jones said Robert Page was well respected in the community.

“This is a shock for all of us that something so brutal could happen,” Jones said.

Ponce Martinez is facing a murder charge and additional charges may be filed because of what Hammer described as “incidents at the police department.”
