A 15-year-old left to get a drink on Halloween night but never returned.
The next day, her remains were found in a sand pit. Even three decades later, her Halloween night killer remains unknown.
On Nov. 1, 1987, two fishermen found the body of Shannon Olson floating in a pond at 29th Street and Hydraulic Avenue, according to police in Wichita, Kansas. The 15-year-old was stabbed several times in the chest.
She also had her throat slashed and her hands were tied behind her back, police said.
Investigators said Olson left to get a drink on Halloween and never returned home.
According to KWCH, police said there were signs of a struggle near the pond where Olson was found. But investigators have never made an arrest in the case.
Authorities have kept a lid on many details of the case, choosing not to release them to the public. They also haven’t disclosed if there are suspects in the case.
Likewise, a possible motive for the teen’s Halloween murder has never been released.
Even though her murder happened 15 years ago, police and Olson’s loved ones still hope to solve the case. In 2019, Tammy McReynolds told KWCH that she was supposed to have a sleepover with her friend, Olson, after they went trick-or-treating. That sleepover never happened.
"She said she wanted something to drink, and we were only a couple blocks away, so we didn't think anything of it. She said she would be right back and we never saw her again," McReynolds told the outlet.
Anyone with information on the Halloween cold case is asked to contact police at (316) 268-4379.
“You never, you never give up,” McReynolds said, according to KWCH. “It’s time fi somebody knows something they got to come forward.”
