Nashville Mass Shooter Devastated by Friend's Death Before Murders

The Nashville mass shooter was reportedly torn up over the death of a close friend months before unleashing a murderous attack at a Christian school.

Audrey Hale was totally devastated after Sydney Shere Sims was killed in a car crash in August, former classmate Samira Hardcastle told NBC News.

Hale “definitely admired” Sims as they together attended Isaiah T. Creswell Middle School of the Arts and the Nashville School of the Arts, Hardcastle said.

Maria Colomy, one of Hale’s former teachers at another school, recalled that Sims’ untimely death was an emotional wrecking ball for her former student.

Colomy paraphrased Hale’s social media posts about the accident, stating something to the effect that Sims was “all that mattered” and “I’ll miss you forever.”

As we reported … Hale went on a bloody rampage at Covenant School on Monday, fatally shooting three 9-year-old students and three employees in their 60s.

Two Nashville police officers shot and killed Hale on the second floor of the private elementary school.

Cops said Hale penned a manifesto detailing the school attack and identifying other potential targets.

Police Chief John Drake said Hale — a 28-year-old biological female who identified as male — was a former student at the school and resented having to attend classes there.
