A high school student from Franklin Square was left at a mini-mart by himself after becoming sick on a class trip.

The Smith family says their son Billy Jr. threw up on the Greyhound Bus shortly after it left Carey High School on Nov. 21. About 60 students were heading to Medieval Times in New Jersey at the time of the incident.

Tricia Smith says the chaperones, who were Billy's English teacher and guidance counselor, called her and said they were leaving her sick child at a mini-mart with the gas attendant because they didn't want to be late for the events.

"They weren't thinking," said Tricia Smith. "They neglected him. It was inappropriate. I wouldn't do this to a stranger on the street."

The Smiths say the school principal and superintendent were unaware of the incident until they confronted them about it. The Smiths told News 12 that school officials were apologetic, but didn't provide details about how the district was going to deal with it.

The family showed up at Wednesday's school board meeting to get answers. The Sewanhaka School District's attorney says the board is working on rectifying the situation.

"The Board of Education will review the field trip policy and in addition, central administration in conjunction with the Board of Education is developing a field trip manual," said Noah Walker, Sewanhaka School District's attorney.

The attorney says once the field trip manual is completed, it will be provided to staff and parents.
