By Amy Cherry/Mellany Armstrong 6:40pm, September 30, 2013 - Updated 9:13am, October 1, 2013Colonial School District is on high alert after receiving what school officials are calling a credible threat.
Superintendent Dorothy Linn tells WDEL the threat came into George Read Middle School Monday.
"There was a note that was put into our student advisor's mailbox in the main office, and the note had a statement that said, 'Mr. Jones, I'm going to bring a gun into school tomorrow to kill people,'" says Linn.
It's believed a student is behind the threat, and police are using fingerprint analysis to determine the student's identity.
Delaware State Police tell WDEL Tuesday morning they have made no arrest in the case.
WDEL's Mellany Armstrong reports there was a heavy police presence outside the New Castle school Tuesday, students subject to having their backpacks and persons searched.
Linn says parents shouldn't be afraid to send their kids to school, but she understands their concern.
"If they are not comfortable sending their kids to school tomorrow (Tuesday), then it would be an excused absence, so we are fully aware that a lot of students may not come to school tomorrow out of safety," says Linn.
500 of 700 students didn't show up for class Tuesday.
