CARLISLE, Pa. (AP) – Authorities are trying to determine whether a truck driver who disappeared from a Cumberland County truck stop – leaving his cell phone, keys and wallet inside the unlocked vehicle – may be a man being treated for amnesia in a Miami hospital.

Bert Delaney Williams III, 27, a father of two from Waterbury, Conn., has been missing since at least Wednesday, when police were alerted to his rig parked at the Flying J Travel Plaza in Middlesex Township, authorities said.

“We found all his personal effects except for his driver’s license,” said Middlesex Township police Officer Paula Mullen, who said the disappearance was being treated as a missing persons case.

Following nationally televised news reports about the search, a Florida television station called the family to say they had been contacted by a Miami hospital about an amnesia patient who showed up Friday, Mullen said Sunday night.

Mullen said the family told police that the man in Miami has the same eye color as Williams and the same tattoo on his left arm of a cross of bones intertwined with snakes. The family was told the patient was sunburned and said his legs hurt from walking, police said.

“Our next step is to get confirmation that it’s him and have a detective down there talk to him,” Mullen told The Patriot-News of Harrisburg. She said a fingerprint match would be attempted Monday.

Williams was driving the rig, which was carrying a partial load of frozen food, for MTS, a trucking company in Wilson, Wis. He was on his way from New Jersey to Ohio to pick up more cargo, Mullen said.

When he failed to arrive in Ohio, MTS officials checked the cash advances they issued on his toll card. The last advance was taken Monday evening at the truck stop, where MTS officials tracked down the rig and contacted police.

Mullen said authorities have no idea how Williams, if it is the same person, could have gotten from the Pennsylvania to the Miami hospital.
