FRANKLIN SQUARE, N.Y. – Tricia Smith is demanding answers, but the Sewanhaka School District doesn’t have any to offer.

District officials are reviewing and crafting a field trip handbook after Smith’s son, Billy Jr., was left with the attendant at a mini mart during a trip with about 60 students from Long Island’s Carrie High School to Medieval Times in New Jersey Nov. 21.

Billy Jr. got sick on the bus and threw up, so chaperones called his mom and left the 16-year-old behind so they wouldn’t miss the events, News12 reports.

“They weren’t thinking,” Trisha Smith told the news station. “They neglected him. It was inappropriate. I wouldn’t do this to a stranger on the street.”

And she’s not the only parent fuming.

“You trust the teachers and the principals, you entrust them to take care of your children when you’re not there and them to leave them at a rest stop is ridiculous,” another woman told CBS.

Smith attended the recent school board meeting to air her grievances after the family contacted the superintendent and school principal, and were disappointed with their inaction.

School officials apologized, but didn’t offer any solutions to prevent it from happening again, Smith told News 12.

Board members at Wednesday’s meeting told the Smiths they’re now working on fixing the problem.

“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,” district attorney Noah Walker told the news station.

The incident spawned outrage from parents on Facebook.

“I’m sorry, but sick is sick no matter how old you are. How sick? Who knows?” Edgar De Castro wrote. “Being left alone while you are ill at any age can get scary very quickly. What if he had a seizre? Heart attack? You never know.

“Don’t tell me in the history of field trips that there is no protocol and that leaving a student at a location … is policy.”

“Tell me how the board of education is going to try to justify this one …,” Anthony Saponaro posted.

Rosanna Aris was amazed chaperones didn’t have more common sense.

“A field trip manual? What is wrong with these people?” she posted. “They are adults we trust with our kids … you don’t leave a kid behind, it’s pretty simple to me.”

Others believed that someone should be held accountable.

“There should be consequences to the staff that left the child behind!” Tara McCabe Casucci wrote.
