YOUNGSTOWN, Ohio - The Arizona trucker has been declared incompetent to stand trial for a 1992 cold case murder in Austintown, at least for now.

Relying on mental evaluation reports from two doctors, Mahoning County Common Pleas Judge John Durkin ordered that 49-year-old Samuel Legg III undergo treatment at the Twin Valley Behavioral Health Center for the next four months, after which time Legg will be re-evaluated.

Legg faces charges of aggravated murder, aggravated murder during the commission of a felony (rape), aggravated murder during a felony (robbery), and murder. 

Legg previously pleaded not guilty to the charges.

Legg was charged in February in the 1992 murder of Sharon Lynn Kedzierski. 

On April 9, 1992, the body of an unidentified white female was found near the edge of the Universal Truck Mall parking lot in Austintown, Ohio.

She had been deceased for approximately 24 hours and died as a result of multiple blunt force injuries to the head, face, and upper chest. 

Officials say Kedzierski was clothed in a well-worn, short-sleeved blue shirt, men's brief-style underwear (size small), and a white tube sock with three dark blue stripes at the top.

A woman's calf-high brown leather boot (size 10) and a blue baseball cap with the logo "Lesco Truck Rental, Chattanooga, TN" was found nearby. This woman was later identified as Sharon Lynn Kedzierski, of Florida. 

Officials say Kedzierski was last seen in Florida alive in 1989. 

Several years later, Gains says Kedzierski's daughters reportedly submitted their DNA to the National Missing and Unidentified Persons System (NAMUS).

Prosecutor Gains says that donation of their DNA was instrumental in identifying Kedzierski. 

In 2011, a Mahoning County Coroner's Office investigator sent evidence to the Ohio Bureau of Criminal Investigations, including the DNA samples taken from Kedzierski's body. 

In 2013, DNA evidence from the investigation linked to an unknown male came back related to crimes in other places as well as Kedzierski's case.

Evidence suggested a truck driver was the suspect. That truck driver was later identified as Samuel Legg, III.

Legg is also charged in connection with a 1997 rape case in Medina County.

The charge of aggravated murder carried a potential sentence of 20 years to life in prison in 1992, which is what he would be facing.
