juvenile detention center

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.

Gynnya McMillen was discovered unconscious at the Lincoln Village Regional Juvenile Detention Center in Elizabethtown, Ky.
