A Florida man has been charged with concealing a body on a military post and four other crimes in connection with a body that was pulled from a lake at Fort Riley last spring.

Federal prosecutors said Christopher Anthony Wilaby, 26, of Pensacola, has been charged in the death of Echo May Wiles, whose decomposed body was found in the back seat of her car on April 15 in Moon Lake.

A criminal complaint filed in U.S. District Court in Topeka charged that Wilaby strangled Wiles at a trailer court in Junction City in August 2005. The two had been involved in a relationship, the complaint said.

Prosecutors said Wilaby loaded Wiles' body into her car and drove it onto Fort Riley and into the lake.

The body was found nearly five years later after a construction worker noticed the car's antenna after the lake had been partially drained for a construction project, prosecutors said.

Wilaby also was charged with stealing Wiles' car, failing to report the theft of a car, obtaining control of Wiles' body, and entering a military installation for an unlawful purpose.

The charges do not allege that Wiles' death occurred on federal property. Federal prosecutors said the Geary County Attorney's Office is assisting with the case.

Wilaby is in custody in Pensacola.
