CHARLOTTE (AP) _ The FBI was investigating the disappearance Sunday of an armored-car company employee, a white van and up to $15 million, authorities said.

David Scott Ghantt, 27, of Kings Mountain, is a driver and guard at the Loomis, Fargo & Co. facility in west Charlotte.

FBI special agent William Perry said Ghantt worked there Saturday night. But he was reported missing about 7:15 a.m. Sunday morning by his wife, according to Charlotte police Capt. Randy Johnson.

Company officials reported the missing money and van at 9:10 a.m. Sunday.

Police found Ghantt's red pickup truck unlocked near the armored-car company's building, Johnson said.

After checking the inside of the building, police sent out a bulletin alerting officers to watch for a Ford Econoline van that could be carrying as much as $15 million.

``We aren't sure how much is missing,'' said FBI spokesman Bob Wanamaker. ``You can't make a count that fast. We do know it's a very substantial amount of money.''

Police listed the crime as ``larceny by employee'' and ``auto theft,'' but FBI agents hadn't ruled out the possibility that Ghantt is a victim in the crime.

The theft would be the second this year involving Loomis, Fargo & Co.

On March 29, Philip Noel Johnson, 33, a former Loomis, Fargo & Co. driver, allegedly took more than $18 million from an armored car vault in Jacksonville, Fla. in one of the largest heists in U.S. history.
