A Highland Park High School student found a handful of .22 caliber bullet shells in a bathroom Wednesday, and the school's 2,000 students were sent home early for the second consecutive day.
On Tuesday, a threatening note was found in a different bathroom -- the fourth such threat in the last two months.
School district spokesperson Helen Williams said school will start at the standard time Thursday morning -- with stepped-up security.
“The City of UP (University Park) has generously offered to send extra officers to be here throughout the day,” Williams said, “and we will limit the places students can enter and leave the school.”
“We are also restricting access to the bathrooms because all of these notes and items were found in the bathrooms,” she said.
Authorities are also reviewing video recorded by hallway cameras as they continue their investigation into the threats.
Williams says the Highland Park District is using a text messaging system as well as email and the district website to keep parents informed.
