(WMC-TV) - The retrial of a Memphis man, previously convicted of murdering a police officer, spilled out into a rare weekend hearing.
Timothy McKinney, the accused killer, is back in court sixteen years after the death of veteran Memphis police officer Don Williams.
Defense Attorney Gerald Skahan said the years that have passed take a toll.
"Witnesses have passed away, the procedures have changed, witnesses have said many different things. It just makes it more difficult," said Skahan.
On day six of the retrial Saturday, the defense questioned police about evidence contamination.
"What the evidence showed [is] that the evidence was laid on the evidence room floor of the jail before it was sent off for testing. It's up to the jury to determine if that infected the evidence," said Skahan.
Prosecutors Thomas Henderson protested the direction the trial is taking.
