A 20-year-old man and a juvenile female are jailed after a man's tortured body was found at a northwest Missouri lake.

The victim, 58-year-old Mark Thomas of Liberty, was found dead early Sunday at Smithville Lake. Court documents say his body was found inside a park restroom with his ankles bound, a bag wired around his head and a ring finger partially severed. He died from a blow to the head.

The Clay County prosecutor's office says Zachary Lisle is charged with murder, kidnapping, robbery and armed criminal action. His bond was set a $1 million. Online records do not indicate that he has an attorney.

The Kansas City Star reports the prosecutor's office did not specify what charges the female might face.
