STUART, Fla. -- Martin County authorities said that new evidence has solved a 16-year-old murder case.

Sheriff's deputies said Wednesday that they believe that Omar Johnson and Daryl Cheatham were involved in the killing of 34-year-old Allan Matzek.

They said Johnson shot and killed Matzek at a Stuart rest stop in November of 1991. Three other accomplices helped dump the body into a nearby grassy area.
