According to the affidavit Stigall was in her room at the Fairfield Inn in Evansville early last Monday morning when Joseph Nelson told her he wanted to "play around." Stigall says she was uncomfortable with the remarks and called David Lackey to pick her up. Shawn Grigsby was in the car with Lackey when the two picked up Stigall and Nelson. The four of them then went to the Huck's gas station on North Green River Road and Lynch Road where they picked up Stigall's brother Matt McCallister.
Stigall says McCallister said to Nelson "Brother I don't know what God or what sort of any kind you believe in...But I suggest you start making amends with him now."
The five then drove east on Boonville-New Harmony Road in Warrick County. Near a railroad track everyone got out of the car. Stigall says Nelson was told to get on his knees and put his hands behind his back. According to the affidavit then McCallister shot and killed Nelson.
The affadavit says Stigall drove to Evansville where McCallister dumped the gun in a storm sewer on Pollack Avenue. The affadavit says officers were later able to find a Taurus handgun from the sewer. Lackey led officers to the location of the shooting in Warrick County where officers say they found a single shell casing.
The train car Nelson was transported in was in transit from northern Warrick County to the Alcoa Power Plant that same morning. However the affidavit does not say how Nelson was put in the car.
We found this exchange between Stigall and Lackey on Facebook three days before the murder. Stigall says "Just wanted to let you know how much I appreciate your love and everything you do. Happy Valentine's Day." Lackey replies "I feel like you're the only one for me."
Grigsby, Stigall, and Lackey will be in court Thursday where they are expected to be charged with murder and conspiracy to committ murder.
