Mattingly, who had reportedly struggled with substance abuse for many years, was found unresponsive by police at her home in the city of Austin after a concerned friend contacted the authorities to check on her after she abruptly dropped contact.

In an official statement, per The Metro, her surviving family wrote: "We learned late Thursday night that it is believed that our dear sister with a larger-than-life personality took her own life. Ashley moved closer to home a couple years ago and was living in Austin. It’s maybe no secret that Ashley struggled with alcohol and substance abuse, but she wanted to and was working to get better."
