CLAYTON, MO (KTVI)- Seven school districts are asking St. Louis County Prosecutor Bob McCulloch to carefully consider when he releases the findings of the Michael Brown grand jury. They are raising safety concerns for students.

A spokesperson says McCulloch has received this letter and is considering it.

The letter was sent by the Riverview Gardens School District but was also signed by six other superintendents. The letter asks McCulloch to announce any grand jury decision either after 5p.m. on weekdays or on a weekend, preferably on Sunday.

The letter is dated October 22nd.

It references how the release of past information along with protests and the police response have forced road closures and made it difficult for students, parents and school buses to make it to campuses. The letter says school districts are expecting similar issues when the grand jury decision is announced and that information released during the school day has the potential to greatly affect school district operations.

The letter asks McCulloch to refrain from making any grand jury announcement until all students get home safely.

You`ll recall the Ferguson-Florissant School District had to delay the start of school by nearly two weeks back in August because of the Ferguson unrest.

Riverview Gardens also had to cancel some days at the start of the school year.

A spokesperson for McCulloch says the letter has been received and it is being considered.

The superintendents tell McCulloch that travel routes for roughly 20,000 students in seven different districts could be impacted.
