I talked to Hardings sister and she had this to say:
"Hey everyone, this is Hardings sister. As many of you know now, Harding passed away a few days ago. It is a huge shock to everyone. I am not releasing any details because we don't even know anything yet. All I can say is Harding passed from an unnatural cause. Please just keep my family in everyones Prayers, rest in peace, Hardy."
