For example, six days after the murders, Park employees emptying out trash bins in the forest discovered that none of the receptacles had been secured by law enforcement at any point after the crime. While making their rounds, these employees had unknowingly discovered a major piece of evidence just sitting in one of the bins.

It was the plastic grocery bag that Lena and Stina Sophia had taken with them when they went swimming. According to what an investigator and lawyer told producers for the Banahaya killings docuseries, it took another week after the park workers collected the trash bins for the police to actually go through them.

So investigators were way behind the eight ball by the time they got their hands on the plastic grocery bag evidence. And just like the used tarp situation, some members of the press criticized the police for the trash bin mistake. But be that as it may, what's more important in the overall scheme of things is that authorities did eventually secure the grocery bag as evidence.

They determined that it had been discarded in a bin near a football field on the northeast side of the park next to a neighborhood of Christianson called Egg. The football field took roughly eight minutes to walk to from lake number three. So it was a feasible distance for the killer or killers to have traversed after the killings if they were the person who put the bag there.

With the crime scene processed and the plastic bag in their possession, the police continued to try and find everyone who'd visited Banahaya on the evening of the crime to see if anyone suspicious had been seen in the key areas of interest. They spoke with several witnesses who helped them narrow down the timeline of when the murders had taken place.

One witness who'd been walking on a trail that led from Stina Sofia's neighborhood to Lake No. 3 said that around 6.35 p.m., they'd bumped into the girls as they made their way to the swimming hole. Authorities also interviewed two university students who said they'd been swimming at Lake No. 3 around 6.35 p.m., and they also remembered seeing Lena and Stina Sofia.

The students told police that they'd left around 6.50 p.m., and when they last saw the two girls, they were playing in the water by themselves. Another witness who came forward said they'd been out for a run and made a lap around lake number three at around 7.05 p.m. However, they didn't remember seeing anyone in the water at that time.

Several witnesses who'd also been at lake number three around seven o'clock reported the same thing, that the girls were not in the water. So taking all of these statements into account, the police realized that whatever had happened to Lena and Steena Sophia had most likely occurred sometime between 6.50 p.m. and 7.05 p.m.

As part of their investigation, they checked in with several known sex offenders in the city and canvassed an area of Christianson that was a known hangout for substance users. But no concrete suspects emerged. Authorities even looked into patients at a psychiatric hospital in the Egg neighborhood. But just like with the canvas of the registered sex offenders, no one surfaced as a viable suspect.

Other efforts by the police to try and identify the perpetrator or perpetrators involved checking local ferry and air manifests and license plates on cars, as well as looking at surveillance footage, but it seemed like no matter how wide of a net they cast, nothing helped push the investigation forward.
