Later that day, an undercover investigator assigned to watch a house noticed that the garage had been damaged and saw the individual backing out of the driveway. The investigator followed him to a nearby gun shop where additional investigators, who were called to the scene, observed the individual purchasing a 9mm handgun and ammunition.
"We were under the assumption that he was purchasing a gun to probably harm himself," lead investigator Frank Stubbs told "48 Hours."
The individual was detained as he walked from the store to his car. The investigators turned him over to military authorities for a mental evaluation.
Suspicious items
Meanwhile, investigators returned to the house with a search warrant. They found the items the individual had purchased from Lowe's that morning which included that shovel and ax, as well as a hatchet, heavy-duty large trash bags, gloves and two 5-gallon gas cans. In a nearby trash can, they found a torn receipt for the items.
The shopping list
Investigators would later obtain a handwritten shopping list Andre McDonald had on him when he was arrested. The list includes many of the items McDonald purchased from Lowe's. Stubbs told "48 Hours" it appeared Andre McDonald entered Lowe's with a sinister plan.
"It doesn't appear that he's going to do yard work … at least not with his wife missing," Stubbs told correspondent Peter Van Sant. "It appears to us that he's going to use these things to dismember her body …"
