MORRILTON, Ark. (AP) – Bone fragments and skeletal remains have been found in a rugged area of Petit Jean Mountain where the skull of missing Little Rock businessman John Glasgow was found earlier this week, according to Arkansas Parks Director Greg Butts.

The skull, found Wednesday by hikers, was identified through dental records as being Glasgow, who was 45 when he disappeared in 2008.

Butts told the Arkansas Democrat-Gazette that rain forecast to continue through Sunday morning was hampering efforts and the search would resume Monday.

“It has been pouring rain. We’re not searching for someone who is injured and needs to be rescued,” Butts said. “It needs to dry out. We will be picking up each leaf and doing a very careful, gentle raking.”

The more remains that are found, the better the chance of determining the cause of death, state Crime Laboratory Director Kermit Channel said.

“We will rely on law enforcement to continue their investigation and search. As they discover additional human remains, they will be submitted to us to examine,” Channel said.

The remains were found within a mile of where Glasgow’s vehicle was last seen parked at the time of his disappearance. That mile, however, is “as the crow flies” and includes lengthy, boulder-laden, steep trails, Butts said.

When the recovery efforts resume Monday, officials will begin more intensive searching that will include cadaver dogs and metal detectors.

“We even have an archaeologist that will be coming with the Arkansas State Police,” Butts said. “They will work to determine how far the remains have been distributed and what to look for after so many years have passed.”

Glasgow, the chief financial officer of CDI Contractors LLC, was last seen leaving his Little Rock home on the morning of Jan. 28, 2008.

The firm, owned by Dillard’s and the estate of co-founder Bill Clark, built or remodeled many of Dillard’s 300-plus department stores and put up some of Arkansas’ signature projects, including former President Bill Clinton’s library and the headquarters of Heifer International.
