Police hope a $250,000 reward will help them find the body of Bowen teenager Rachel Antonio, 16 years after she disappeared.

A $250,000 reward previously offered to catch a Queensland teenager’s killer will now be used to try to find her body.

Queensland police hope the reward could lead them to the remains of Rachel Antonio and give her parents the chance to lay her to rest, 16 years after she disappeared.

The 16-year-old vanished after being dropped off at a Bowen cinema on Anzac Day, 1998.

She was last seen walking on Queens Beach Esplanade just before 7pm.

Previously the reward money was only available to anyone who provided information that led to the arrest and conviction of her killer.

Former surf lifesaver Robert Hytch was convicted of Ms Antonio’s manslaughter in 1999 but was acquitted following a retrial in Townsville in 2001.

Ms Antonio’s parents Ian and Cheryl have requested a coronial inquest into their daughter’s disappearance.

The request has been granted but a date is yet to be set.
