Police in Illinois say Delia Ann Stacey's family received a cryptic, one-word text message from her on the day of her disappearance -- "help."
Stacey, 18, was last seen at her Herrin home on the morning of Dec. 28. According to the Herrin Police Department, the young woman said she was going to meet a friend and left home on foot.
What happened to Stacey after she left remains a mystery. It was later that day that her family received the disturbing text message and there has been no further contact from the teen.
"Further contact with Stacey via her phone has been unsuccessful, as has the use of all resources available in determining her location," Herrin police said in a Thursday press release.
Despite the ominous text, police have not yet said whether they suspect foul play in Stacey's disappearance.
Delia Ann Stacey is 5-foot-6 and approximately 130 pounds, with auburn hair and brown eyes. She was last seen wearing a grey shirt and blue jeans.
Anyone with information on her whereabouts is asked to contact Herrin police at 618-942-4132.
Correction: An earlier version of this story mistakenly identified Indiana as the state where the teen is missing.
