Three witnesses testified in front of jurors during the second day of the Timothy McKinney retrial on Wednesday.
Ronald Marshall, a Memphis police officer, took the stand. He was at a comedy club on Christmas night of 1997 to deliver keys to his cousin while he was on duty.

McKinney, a death row inmate who was convicted in 1999, is accused of shooting Memphis policeman Don Williams, who was working security at a Memphis comedy club on Poplar Avenue Christmas night in 1997.
However, that conviction was overturned and McKinney was granted a new trial that ended with a hung jury in April 2012.
Video testimony of Marshall's cousin, Reginald Lambert, who lives and works overseas, was also presented in court today.
Debra Kimble, McKinney's girlfriend at the time of the fatal shooting, also testified.
With this case being more than 15 years old, the three witnesses had a tough time remembering details of the night in question, even though many of them have answered some of these same questions several times.
