It was in May this year that a vacant policeman took an evening walk at Mälarbadet.
He then reacted to the fact that flashlights were shining in the forest and that he heard chopping sounds.
He called his colleagues who were on duty and a dog patrol could then find a buried gun of the brand Glock in the woods.
Spoke freely in chat
The two men deny the crime but can, according to the prosecutor, be linked to the gun.
As proof of support, there are chats from Enchrochat, an encrypted communication tool used by criminals throughout Europe.
French police cracked the service earlier this year, and for a couple of months this spring, European police and prosecutors were able to read millions of messages in real time.
This is the first time that chat conversations from Encrochat are being tried by the Swedish legal system.
