And then, there was a cracked-out night when they got serious about it. According to one source they had been smoking joints laced with crack, (sources here vary about whether or not crack was involved) and came up with the plan. They decided to lure Holly’s grandparents downstairs by smoking weed, then kill them. Holly even wrote the to-do list on her arm: “Kill, keys, money, jewelry.” They practiced by stabbing pillows.
The murder was brutal. First, Holly stabbed her grandmother and when her grandfather came barreling down the stairs, she fought and stabbed him as he ran to the phone and lobbed a coffee cup at her. She killed both of them. Holly reported having to jump over a pool of blood to leave the house.
After the girls found some jewelry, grabbed the keys and they took the truck on a joyride. They chain-smoked Newports and drove to a beach town. It wasn’t long until they were found. Both girls admitted to the crime.
Sandra received a life sentence and Holly two life sentences. When the judge demanded to know why they killed Holly’s grandparents she said she did it for Sandy, so they could be together. Just anywhere, together.
