ROBERTSDALE, Alabama - A decapitated head, another arm and hand, a leg and a foot were found by underwater search and rescue crews late Monday, and authorities believe they match the identity of an elderly man over age 60.

Authorities are requesting anyone who might know someone that fits the description of the missing man to contact the Baldwin County Sheriff's Department.

According to Sheriff Huey "Hoss" Mack, during a news briefing Tuesday at the Sheriff Department's Robertsdale office, investigators are seeking the victim's identity that has the following characteristics:

White male over the age of 60

Approximately 150 pounds, 6 foot and 1 inches in height

Dentures in the upper and lower parts of the mouth

The victim had a pacemaker, which investigators are examining

A distinctive mole on the right upper sideburn

Balding, greyish hair

Chin hair, and possibly the remnants of a thinning beard.

The man's body parts were found covered and underneath the Nolte Creek Bridge along County Road 26. Volunteer underwater divers with the North Baldwin and Daphne search and rescue units found the body pieces between 8:30 to 10:30 p.m. Monday.

Mack said he believes the body parts were dumped in two separate locations - at Nolte Creek and Weeks Creek, which is where the man's torso was found Monday morning.

The discovery of a human lower arm and hand on Sunday at the Lipscomb Road home of radio station president Clark Stewart triggered the investigation.

Mack said cadaver dogs led searchers to Nolte Creek.

"It's the natural progression of the search," he said. "Lipscomb Road is in the area of that. Our search grid extended out three miles and everything within that."

He added, "We believe its two different locations (where the body was discarded). The water connection is not navigable (between Weeks Creek and Nolte Creek). We are dealing with two different locations."

Mack also said he has no reason to believe there were any other victims aside from the elderly man.

He also doubts that the crime was committed in Baldwin County.

"At this point in time, we are operating on the theory that this individual died in another location and ... these two sites are treated as dump sites," Mack said. "

But he urged the public to come forward if they know a senior citizen who might live themselves.

"Baldwin County is a transient county," Mack said. "We have a lot of people coming and going. (But) we have a lot of senior citizens living by themselves and we have a lot of senior citizens who might be checked on every few days. Once again, that's why we are urging people that if you know an individual who fits these characteristics to check on that person."

Authorities will continue investigation the County Road 26 area and search for the remaining missing foot - Mack declined to say whether it was the right or left foot. No clothes have been recovered, aside from a Tungsten ring that was found on the fingers of the severed hand found Sunday at Stewart's home.

Mack also said there were no visible wounds on the man, including any gunshots.

"It's a homicide," he said. "The dismemberment of a human body, for whatever reasons whether to shield identity or there could be a more sinister reason. We don't know."

An autopsy on the body parts is being conducted Tuesday, although Mack said it could be Wednesday before any cause of death is determined.

Mack said the focus is for authorities to make an identification on the man Tuesday in order to trigger any kind of criminal investigation.

"It's so important for us to identify this individual, as history tells us in these types of investigations, the identity of this individual alone might identify the suspect," Mack said.
