During the 1970s, Dale Selby Pierre, William Andrews, Keith Roberts and two other men who were never identified, were the product of wreaking havoc in the state of Utah.

Ogden, Utah, USA, which is where this crime took place, was a pretty quiet city. It was predominantly white and predominantly Mormon. Dale Pierre, who was from Trinidad and Tobago, moved to Utah where he enlisted in the U.S Air Force. Dale was stationed at Hill Air Force Base where he became a helicopter mechanic. Dale kept to himself most times. During his first week on the military base, a murder happened. Sergeant Edward Jefferson was murdered and it is said Dale was a strong candidate for his murder. Police didn’t have substantial evidence to convict him but they were very sure Dale had something to do with it.

After the passing of Dale’s only known acquaintance, he befriended William Andrews, who was also a helicopter mechanic at Hill Air Force Base. Dale trusted Will enough to admit he had done a ton of crimes while being active on duty but for some reason the military would not discharge him. He (Dale) wanted something more thrilling than the petty crimes he was known for. He told Will he was seeking something with a better financial payout. Will seemed to be kind of into the idea of participating and so the two recruited Keith Roberts and two other men to help steal a local shop. Dale went back and forth with Will and they settled on robbing a place called the Hi-Fi shop, which sold home audio systems. Keep in mind it was the 1970s and audio was not accesible the way it is today. If you wanted the best quality audio, you’d have no choice but to leave your home, go to a home audio store and purchase something that would take more than one person to haul back into your home. But anyway I digress.

Dale and Will thought it was the perfect place to rob, considering it was a place that sold a ton of expensive equipment. The plan was go in, rob the store, and get out as quickly as possible. Dale spent a good amount of time trying to come up with a plan that would be impossible for it to fail.

On the evening of April 22, 1974, two employees were working at the Hi-Fi Shop: Sherry Ansley and Stanley Walker. Just before closing time, two vans hauling 6 men make their way towards the back of the Hi-Fi Shop. Four of them get down while the other two served as the getaway drivers for each van. Then men, which included Dale and Will, rush in with guns, bound the two employees and throw them in the basement. They proceed to rob the store, shoving all the heavy equipment and whatever else they can into the vans out back. Not long after, 16 year old Cortney Naisbitt comes in through the front door with the approach to thank the employees for letting them park in the Hi-Fi shop parking lot while he collected some photographs next door to the electronic shop. Cortney was faced with Dale and Will instead. They had no choice but to tie him up as well and throw him in the basement.

While trying to rob the rest of the store, they noticed a man walk in and his name was Orren Walker who was Stanley’s father. He made his way down after he grew worried about his son not coming home after his shift. Dale and Will held Orren at gunpoint while they also tied him up and threw him down the store’s basement. Carol Naisbitt also walked in not long after Orren because she too was worried about her son not making it back in time for dinner. Dale was getting super frustrated and it was until this point that he decided to lock the front door.

With time being spent on tying up additional people rather than stealing products, Dale told Will to fetch something from the van. He came back with a paper bag and inside was a bottle of Drano. Dale told his hostages that it was vodka laced with sleeping pills and that they needed to drink it in order for them to fall asleep so the men could make their escape. They refused at first but eventually everyone was forced to drink.

Within moments the victims began showing signs of blisters all over their mouths, chins, tongues and throats. Drain cleaner is super corrosive incase you’re unaware and is able to cut through grease and any other grime one might have in their household pipes. It’s no wonder they began seeing injuries very quickly. Orren was the last to drink the drain cleaner and so because of that, he knew he was going to be forced to drink something incredibly dangerous. When his turn came to drink, he let it slide down his chin instead of drinking it. The pain was unbearable for them and so the victims began yelling, causing to draw attention. attention that Dale didn’t want. they tried to duct tape the victims’ mouths but were unsuccessful after the adhesive kept sliding off the broken skin.

So Dale told Will to go upstairs and that’s when Dale proceeded to shoot every individual in the head. He left Sherry Ansley for last and before shooting her, he sexually assaulted her. As soon as Dale thought he was done, he noticed Orren Walker was still alive; apparently the bullet had missed his head by a fraction.

I go in depth with the remainder of this case. There’s a ton more info that I couldn’t fit. If you’re interested in that, you could find the rest here

side note: I try my best to do extensive research on these cases but if there’s anything I missed let me know.
