The Monroe County Sheriff's Office Tuesday announced it would close its investigation into a message found in the bathroom of Honeoye Falls-Lima High School last week.

That message threatened a shooting at the high school last Friday.

The district reported that 60% of its high school students stayed home on the day of the threat.

Despite the sheriff's office decision to close its investigation, Honeoye Falls-Lima Superintendent Gene Mancuso said that the district investigation is anything but over.

"I would tell you that I didn't have anything to do with whether law enforcement chooses to move forward or not," he said. "That is a law enforcement question that I would refer to the district attorney and those offices. That's not my department. My job is to educate students and sometimes that education means disciplining students for their behavior."

The shooting did not take place.

Making a threat of this nature has landed other students in other districts in trouble with the law, not just the school district. A student at East High School, another at a city charter school and a third student at Churchville-Chili High School all face a felony charge, accused of making a terroristic threat.

News10NBC asked the sheriff's office why this case is different.

'"A crime has been committed, but there is not enough probable cause, in this case, to make an arrest, absent a confession," Major Lou Tomassetti said in a statement.

"I don't know as a parent what I would do if I got the call that my child had done something like this. It would be very, very difficult, but judgment doesn't help either," said parent, Kristine Brassie.

Brassie sent her four children to school on Friday. She said that this is tough for school leaders.

"I think as far as the investigation goes, I think I'm just going to trust that what is being done is appropriate," Brassie said.
