"Jurors were given "misleading" information in 1994 about a gun tied to Patrick Pursley in the shooting death of a Rockford man, one of Pursley's lawyers said in closing arguments in a Winnebago County court today. As a result, Pursley should be given a new trial, Robert Stauffer of Jenner & Block told 17th Circuit Judge Joseph McGraw. During Pursley's original trial, experts said that a gun connected to
 him was the only one in the world that could have been used to kill 
Andy Ascher. That was "misleading," Stauffer said. Experts no longer say
 that gun tests absolutely prove a certain gun was used in any crime. Stauffer,
 whose firm was contacted to represent Pursley by the Center on Wrongful
 Convictions at Northwestern University, also said new tests show 
bullets and shell casings were not matched to the Taurus gun to which 
Pursley was linked. Stauffer said ballistics testing was the 
"centerpiece" of Pursley's conviction. "Evidence increasing 
(shows) he has been in prison for a crime he did not commit," Stauffer 
said of Pursley, who is serving a life sentence at Stateville 
Correctional Center in Joliet. But
 Steve Biagi, assistant state's attorney for Winnebago County, said 
tests conducted by state experts show the shell casings matched the gun.
 And that's the case, he said, even though experts now are not sure if 
the bullets recovered from the scene are a match. "We believe the 
fact that shell casings have consistently been identified as a match by 
the state would be enough for a guilty verdict" if a new trial is 
granted, Biagi said. McGraw said he will issue a ruling in the case on Feb. 13."
