Langford, who was still employed as the general manager Thursday, did not respond to attempts to reach him by telephone.
Langford, 41, of 10831 Clinton Ave. in Hagerstown, was found guilty on a misdemeanor count of second-degree assault in connection with a Feb. 23 incident at the rink, court records say. Langford was sentenced to probation before judgment, fined $300 and placed on 18 months unsupervised probation, records say.
Langford was found not guilty on another count of second-degree assault in connection with an incident involving the same girl in late 2003.
On Feb. 23, Langford kissed the girl on the lips while employees were singing "Happy Birthday" to her, records say. The girl slapped him on the chest, pushed him away and told him not to touch her, records say.
Though the city owns the ice rink building, the nonprofit foundation runs the rink. The city pays about $114,600 annually for debt service on the building and contributes about $21,000 annually for utility support, City Finance Director Al Martin said.
Mayor William M. Breichner said he does not believe Langford did anything secretly or maliciously on the date in question and was "just trying to wish her a happy birthday." Breichner also said Langford is supervisor of several other female employees who would "vouch for his character."
