PANA, Ill. (AP) — Skeletal remains found in a southern Illinois field near Pana were identified Tuesday as those of a 25-year-old man missing for more than a year.

Daniel Crosby, 25, of Carterville was last seen the morning of Feb. 27, 2020 walking after his vehicle became stuck in a field. His remains were found Saturday during a search involving several law enforcement agencies and volunteers.

Christian County Coroner Amy Calvert Winans in a Tuesday statement said Crosby’s body was identified through dental records and the assistance of a forensic pathologist.

Crosby’s father, Tim Crosby, has expressed fears his death may have been the result of foul play. The family has offered a reward of $5,000 for information leading to the arrest and conviction of anyone who hurt or harmed Daniel Crosby. The investigation into the death is being led by Illinois State Police. Officials say the remains did not show obvious signs of trauma.

The location of the remains is in an area north and east of the last known location of Daniel Crosby and beyond areas previously searched, Illinois State Police said in a news release. Daniel Crosby was visiting Pana to see friends when he disappeared.
