AKRON, Ohio (AP) -- The father of a northeast Ohio man who disappeared three weeks ago is pleading for the public's help to figure out what happened.

Police say 28-year-old Jorry Palm of Akron visited two bars in that city the night of June 8 and then apparently drove northeast toward Niles, his hometown near Youngstown. Officers haven't been able to locate Palm or his car, a bright red Mazda 6. There's been no sign of activity on his cellphone or bank account, stalling the investigation.

His father told reporters that disappearing without warning would be out of character for Palm.

The blond, blue-eyed computer engineering specialist was reported missing when he didn't show up for work at Lockheed Martin. The Akron Beacon Journal reports Palm had security clearance for the government contractor.
