Troopers say 45-year-old Mark A. Carter pulled his car in front of the couple's horse and buggy about 12:20 p.m. Sunday, forcing it to stop. Authorities say Carter got out of the car, went to the couple armed with a handgun, and demanded money.
Police say the couple had no money, and Carter got back into his car and fled. The couple got his license plate number and a traffic stop led to Carter's arrest.
Carter is charged with attempted robbery and other offenses. He is being held on $123,100 cash bond.
