Sgt. Dennis Caputo of the Clark County Sheriff's Department was one of the first officers on the scene. He found a quarter-ounce of heroin in a balloon in the kitchen, and a half-ounce of marijuana in Liston's pants pocket, but no syringes or needles. Some found it suspicious that authorities could not locate any drug paraphernalia that Liston presumably would have needed to inject the fatal dose, such as a spoon to cook the heroin or a tourniquet to wrap around his arm. But former Las Vegas police Sgt. Gary Beckwith said, "It wasn't uncommon for family members in these cases to go through and tidy up ... to save family embarrassment."
