The police are putting together the "puzzle" about the fatal shooting in Botkyrka, says Palle Nilsson.

Technical evidence has been collected and several people have been summoned for questioning. The police are particularly interested in a white van, says Palle Nilsson and urges that the people who have information about this should contact the police.

Whether the girl was a target or not is not something the police want to comment on.

- This early in an investigation, we should not go out with so much information, because it can destroy the investigation. But that is, among other things, the part you watch, says Palle Nilsson in SVT's Morgonstudion.

May have links to criminal networks

According to information to Expressen, the targets must have been two men from a criminal network and the girl must have been hit by a past bullet.

- The risk of a "third man" being affected by this is still very low in a country like Sweden, says Ardavan Khoshnood, specialist in emergency care and criminologist.

- On the other hand, it has increased somewhat in recent years.

The police do not want to confirm or deny the information.

- We do not comment on that. In general, this type of shooting has links to criminal networks, but we do not go into how it is in this particular case, says Palle Nilsson to SVT News.

Children are forced into crime

According to Palle Nilsson, there are about 30 people who are violent in the Stockholm region and these must have connections to criminal networks.

- These people are behind the majority of extortion, robbery, drug sales, shootings, explosions and murders in the region, says Palle Nilsson.

The police in Sweden cooperate with Europol and have been allowed to take part in encrypted material, says Palle Nilsson. It appears that children have been threatened with so-called criminal behavior.

- They threaten children and force children into criminal behaviors such as drugs, violence, shootings. You force a child to shoot a person, otherwise you will go bad yourself. And this we have to work with other authorities. We must find the children who are at risk, says Palle Nilsson.
