The dream is to become a coastal hunter.
Zack attends a high school education with a focus on uniform professions.
In his spare time, he attends courses organized by Försvarsungdom.
But he also has a great interest in military stuff.
An interest that has led to him now being suspected of both weapons offenses and violations of the Military Equipment Act.
But Zack and his parents can't understand how anyone could think he did anything criminal.
- It's starting to feel very surreal, says mother Eva Marklund, who says she feels very unwell and has difficulty sleeping at night.
Nasty Idol's cartridge belt
Last fall, the police came to visit.
Zack was suspected of weapons offenses and theft.
It turned out to be ads that Zack posted on Facebook.
When he was 14, he sold a replica cartridge belt given to him by his father, Peter Espinoza, guitarist in the rock band Nasty Idols.
The father bought the cartridge belt with empty casings in a clothing store after being inspired by Motörhead's Ace of Spades album cover.
- The police report stated that I had stolen ammunition from the Armed Forces and sold it on Facebook.
It is a cartridge belt that was bought in a store about 30 years ago.
It's a clothing accessory, says Zack Espinoza.
Military helmet model 90
The second crime concerns a Swedish military helmet model 90. Zack bought it at a second-hand shop last October.
When he placed an ad to sell the helmet, he was suspected of embezzlement, of dealing in stolen goods.
But when he showed the receipt from the store, suspicions were put to rest.
But then the Swedish Armed Forces filed a new report of a violation of the Military Equipment Act.
Zack's lawyer Rebecca Sofiadotter Lepic is critical of the accusation.
- It is difficult for an ordinary person to understand that what is sold at a second-hand shop can be illegal and covered by the law on military equipment, she says.
Neither the prosecutor nor the Armed Forces want to comment on the suspicions in the preliminary investigation.
