An investigation by Denver Public Schools found that employees at McAuliffe International School, including former Principal Kurt Dennis, violated district policy by placing students in two rooms without proper supervision and either locking or holding the doors shut while doing so, according to a letter summarizing the findings. The district’s Board of Education announced earlier this month that DPS was looking into the use of a “seclusion room” at the middle school, including whether students of color were locked inside alone, after receiving an email from an anonymous McAuliffe employee. The allegations have since spurred two separate investigations by the Denver Police Department and the Colorado Department of Education. “Everything we have told the community has come back to be true,” said DPS board Vice President Auon’tai Anderson, adding, “What happened to those babies should never happen again.” DPS’s internal investigation found that McAuliffe employees were directed to use two rooms for the purpose of “student seclusion” beginning around Nov.
