Rae was found dead in his home Monday morning in the 5100 block of Hannibal Street in Denver, according to a news release from the medical examiner.

In April, Rae brought a gun to school and threatened then-principal Taisiya Tselolikhin and two other administrators.

Tselolikhin was placed on leave following the incident. She resigned in May after an Aurora Public Schools audit revealed she delayed calling police and did not implement campus security precautions when Rae reportedly brought a gun to school.

Rae faced five felony charges and three misdemeanors in connection with the school incident in Aurora and two alleged domestic disturbances in Denver. The charges included attempted first-degree assault with a deadly weapon causing serious bodily injury; attempted first-degree assault with a deadly weapon; possession of a weapon on school grounds; carrying a concealed weapon; felony menacing; kidnapping; imprisonment; and prohibited use of a weapon.

Tselolikhin was listed as the victim in the two domestic disturbances. An affidavit from Denver police said the two had gone to Rae’s house after a work-related event on March 1, and that he had pointed a gun at her chest when she was going to leave, but turned the gun and fired past her. She told police she didn’t initially report the incident because she didn’t want to get him in trouble.

Aurora Public Schools investigated the on-campus gun incident and found that although the incident happened at 1:51 p.m., Tselolikhin didn’t call school security until 3 p.m., and then she refused to lock the school’s doors, the audit said.
