Hicks died the day before. Her daughter, Vel McKee, said the thief yanked off the ring, meant to symbolize her mother's devotion to her husband, Gayle Hicks, who died three years earlier.

The ring was actually a $10 piece of plastic.

"It's being investigated, even though the ring was a $10 plastic ring," Cpl. Steve LeSueur of the Odessa Police Department told USA Today. "Theft of a corpse, regardless of whether it's $5 or $5,000 is still an automatic felony."

The family said they have seen the surveillance video of the theft.

Police said it is not known how the video appeared online. They said they saw the video nearly 24 hours before the theft was reported.

The Sunset Funeral Home in Odessa, Texas, where the theft occurred, said it did not publish the video.

Hick's granddaughter, Brooke Vaughan Burns, has posted the video to Facebook, asking people to share it and an image from the video in order to catch the thief.

"I can’t believe someone would be that low,” McKee said. "It makes me sick to my stomach,” McKee said. "Horrible. I hope they catch her."
