Crime Alert, I'm John Lemley. At this hour, a decades-old mystery remains unsolved in the heartland.

Investigators are renewing calls for public assistance in one of Illinois's most haunting cold cases.

The body of Ullalia-Lali-Shavez was discovered almost 40 years ago in a remote cornfield near Lebanon, Illinois.

On September 6, 1986, a farmer found her nude body off Oak Grove School Road, strangled, and brutally mutilated.

Authorities later learned she had been strangled with her own clothing, and evidence at the scene

suggested signs of extreme violence.

Her killer cut her pelvic area and attempted to remove her reproductive organs, but no suspect

was ever identified.

For more than three decades, the case went cold.

In 2007, the victim was finally identified

as 27-year-old Chavez, a runaway from Palo Alto, California, who had vanished in the mid-1970s

while hitchhiking and following music concerts across the country. Despite technological advances in forensic science,

including DNA analysis and composite imaging, law enforcement has not charged a suspect.

The FBI's violent criminal apprehension program has issued a VICEAICA alert seeking information about Chavez and anyone

connected to her in the months before her death.

Authorities are urging anyone with details, no matter how small, to come forward.
