Lockhart's family shared a statement confirming the coroner's office's report, noting that he "had a sudden and fatal arrythmia."

"After 5 months of testing, the conclusion is that, while Garrett did suffer from depression and anxiety, he did not take his own life," the statement reads. "It is our hope that Garrett's premature death can be used to create and normalize conversations surrounding mental health issues, realizing there may be underlying disease of conditions requiring medical attention."
