Lynch's parents were outraged that their son would have a suspension on his record for the incident.
"I don't think the punishment fits the crime," mother Jeannie Lynch told WJLA.
"They're saying he threatened to shoot a student," said Rodney Lynch Sr. "He was playing."
Lynch was reinstated to the school on Tuesday, following the winter break. Ficker said he is awaiting a response from the school on his request to expunge Lynch's record. If the request is denied, he will seek to take it to a higher authority, he said.
