In the video, which is over 40 minutes long, Davis can be heard to say she had been sexually abused by a family member. She then continued filming as she took her own life in front of her home.

Her family have deleted the video from Davis's Facebook page but Polk County police chief Kenny Dodd told Fox5 his department had been flooded with messages stating the video is circulating on various social media platforms, including Facebook.

However, at the time of writing, anyone who reported one of the videos received this automatic response.

While the video is still circulating on Facebook, it has been deleted from YouTube.

Before her death, Davis posted a video on YouTube titled "To Everyone Struggling With Depression," encouraging viewers to seek help and to remember that it's not their fault.

Many of the diary entries have been deleted but people have screenshot them and spread them online.

Polk County police have also launched an investigation into allegations of abuse and sexual assault that Davis outlined in her videos and her online diary on Dec. 27.

Justice for Katelyn Nicole Davis is reposting older videos Davis made, but the page administrator said they believe the video containing the suicide needs to be taken down: "Because a kid or someone suicidal could see it & get triggered or scarred for life."
