PALATINE, Ill. (WGN) — Police in Illinois are seeking the community’s help related to a missing person investigation that’s been unsolved since 1998.

Anthony “Tony” Klama was reported missing on Nov. 6, 1998, after failing to show up to work.

Klama was last reported seen in the Chicago suburb of Palatine the night before at approximately 11:30 p.m.

Witnesses told police they spotted him near a vehicle with an unknown male, described as white or Latino.

He’s not been seen or heard from since.

Klama was 36 at the time of his disappearance and was 6’1 and weighed around 160 lbs.

He had brown hair, green eyes and a mustache. Klama had Native American-themed tattoos on both arms and on his chest.

On the night he was last seen, he was wearing dark jeans, a blue and white flannel T-shirt and a baseball cap.

In 2014, two “good Samaritans” mailed an anonymous letter to Crime Stoppers about the case.

Police are hoping to speak with them and urge them to come to the department with any information.

Anyone with information can contact local police at 847-359-9000.
