Investigation found that Reginald Windham and Victor Holt didn't perform routine bed checks and falsified records saying that they did.

The death of Gynnya McMillen, 16, in a Kentucky detention center earlier this year sparked anger among civil rights activists as details emerged about her passing. But officials say that the teen, who was discovered in her cell on Jan. 11, died of an irregular heartbeat and not from an altercation with the facility's staff, according to BuzzFeed.

Reginald Windham, a longtime employee of the Lincoln Village Juvenile Detention Center, amassed a record of misconduct, including charges of excessive force and negligence.
