HUTCHINSON, Kan. — An attorney representing Project for Innocence at the University of Kansas filed a 43-page motion on behalf of Trever Corbett. Corbett was convicted of murder for the strangulation death of his ex-wife, Crystal Casey, in 2000.

Evidence introduced during the trial included results of various DNA tests. Some of the DNA matched Corbett, other tests did not eliminate him. Swabs from Crystal Casey’s neck showed DNA of an unknown male. The DNA didn’t match Corbett or Shane Casey, another ex-husband of Crystal Casey who was the first murder suspect.

DNA testing has improved since this case went to trial. While District Attorney Keith Schroeder agrees testing has improved, he doesn’t suspect there would be a different outcome.

Schroeder says DNA was not the only factor used at trial:

 

According to the filing, Corbett wants new DNA testing of the physical evidence including clothing, blood, trace samples and any other collected evidence that may not have been tested before trial or retested based on DNA techniques.

Without DNA, Schroeder believes other factors in the case would have been enough to convict Corbett:

 

District Judge Trish Rose scheduled a hearing for 2:30 p.m. Friday.
