The school had to be shut down for the day after a student took his own life on the campus.
McKinney North High School had to be evacuated on Friday, June 1, early during morning classes after a student from the school died of a self-inflicted gunshot wound in an empty classroom.
On Monday, June 4, classes resumed following the suicide, and the McKinney Idependent School District released a statement saying that extra grief counselors, security, and administrative personel had been made available to the students.
"Students, parents and staff have done exceptionally well today supporting each other," the district told NBC 5. "The overall mood at the school is solemn, but respectful and encouraging"
In the middle of the first day back, the McKinney Police Department shared that they were investigating over 700 tips of threatening posts over social media that had flooded the school.
The Department also reiterated that extra officers had been stationed at all schools across the district as the investigation into the suicide was underway.
"We have found nothing to indicate that the student who took his own life at McKinney North High School on Friday had planned to do harm to anyone other than himself," McKinney police said in a statement.
The police department has released limited information about the death of the student, saying that he had used his father's five-shot revolver to kill himself in a vacant room on the school grounds.
It is the last week of school for McKinney North, and the officers wanted to ensure the safety of the students during the final days.
