Case Facts:

In June 1996, Deck planned a burglary with his mothers boy friend, Jim Boliek, to help Boliek obtain money for a trip to Oklahoma. Deck targeted James and Zelma Long, the victims in this case, because he had known the Longs' grandson and had accompanied him to the Longs' home in DeSoto, Missouri, where the grandson had stolen money from a safe. The original plan was to break into the Longs' home on a Sunday while the Longs were at church. In preparation for the burglary, Deck and Boliek drove to DeSoto several times to canvass the area.

On Monday, July 8, 1996, Boliek told Deck that he and Deck's mother wanted to leave for Oklahoma on Friday, and he gave Deck his .22 caliber High Standard automatic loading pistol. That Monday evening, Deck and his sister, Tonia Cummings, drove in her car to rural Jefferson County, near DeSoto, and parked on a back road, waiting for nightfall. Around nine o'clock, Deck and Cummings pulled into the Longs' driveway.

Deck and Cummings knocked on the door and Zelma Long answered. Deck asked for directions to Laguana Palma, whereupon Mrs. Long invited them into the house. As she explained the directions and as Mr. Long wrote them down, Deck walked toward the front door and pulled the pistol from his waistband. He then turned around and ordered the Longs to go lie face down on their bed, and they complied without a straggle.

Next, Deck told Mr. Long to open the safe, but because he did not know the combination, Mrs. Long opened it instead. She gave Deck the papers and jewelry inside and then told Deck she had two hundred dollars in her purse in the kitchen. Deck sent her into the kitchen and she brought the money back to him. Mr. Long then told Deck that a canister on top of the television contained money, so Deck took the canister, as well. Hoping to avoid harm, Mr. Long even offered to write a check.

Deck again ordered the Longs to lie on their stomachs on the bed, with their faces to the side. For ten minutes or so, while the Longs begged for their lives, Deck stood at the foot of the bed trying to decide what to do. Cummings, who bad been a lookout at the front door, decided time was running short and ran out the door to the car. Deck put the gun to Mr. Long's head and fired twice into his temple, just above his ear and just behind his forehead. Then Deck put the gun to Mrs. Long's head and shot her twice, once in the back of the head and once above the ear. Both of the Longs died from the gunshots.

After the shooting, Deck grabbed the money and left the house. While fleeing in the car, Cummings complained of stomach pains, so Deck took her to Jefferson Memorial Hospital, where she was admitted. Deck gave her about two hundred fifty dollars of the Lung's money and then drove back to St. Louis County. Based on a tip from an informant earlier that same day, St. Louis County Police Officer Vince Wood was dispatched to the apartment complex where Deck and Cummings lived. Officer Wood confronted Deck late that night after he observed him driving the car into the apartment parking lot with the headlights turned off. During a search for weapons, Officer Wood found a pistol concealed under the front seat of the car and, then, placed Deck under arrest. Deck later gave a full account of the murders in oral, written and audio taped statements.
