Three separate threats lead to some extra security at the Shen campus on Monday.
Two messages were found scrawled on a bathroom wall, and another was posted on Instagram.
Saratoga County Sheriff's deputy Ken Cooper says police have to take these threats seriously, especially with the Florida shooting still fresh in people's minds.
The threat may have kept a few more students home than usual.
School officials say it was a normal day.
