SAN ANTONIO -- A 15-year-old girl from the Beaumont, Texas area recently reunited with her family has died, reports CBS San Antonio affiliate KENS-TV. Heaven Cox disappeared from her Orange County, Texas, home in November, sparking a nationwide search. It was suspected she'd left with someone who'd preyed on her on the internet.

Authorities announced she'd been found safe five days later, on November 30, and she was reunited with family members.

Her mother announced her death on Facebook Saturday, saying, "Our sweet Heaven left us to be with Jesus this afternoon around 4:00. Some bright lights are not meant for this dark and cruel world. I know that Dusty and Gracie were there to welcome her. Sing with the angels sweet girl. I love you."
