Torbjörn Granström has been monitoring the criminal environment in Södertälje for several years.
He believes that the violence of the last week largely consists of a rivalry that has developed among the criminals.
- Mainly it's a fight for the criminal market between groups that are literally at full-scale war with each other.
It is also about influence and old grievances.
We have several unsolved murders in the criminal environment in Södertälje for a few years now.
It is partly tone-setting people who have been shot, when they do it there are always effects sooner or later, says Torbjörn Granström.
"Recklessly turn on each other"
He says that the police themselves do not believe that the shootings are about to stop:
- Now there have been a number of murders and then there will be revenge actions as an effect of that.
There is no indication that it will stop.
But you can always hope that when actions are taken on the spur of the moment, in the spur of the moment, that you make mistakes that give the police a chance to come in and get at them.
For several years, Södertälje in particular was brought up as a good example of how the police managed to overcome the violent criminal gangs.
Granström believes that it is divisions that have caused the conflicts to return.
- These are groupings in what we previously rather carelessly called the "Södertälje network".
A network that used to hold together and thus we did not notice this type of shooting death.
Södertälje distinguished itself in the other direction for a few years precisely because it was a unit in the criminal market.
It has now been fragmented.
Now they ruthlessly try to attack each other.
