On Sunday, a homeowner found a dead man in his 20s on his plot in Södertälje.
The man is said to have been in the cemetery to honor a dead relative.
Sunday's event was the twentieth fatal shooting this year alone.
- It is extremely remarkable.
It is a tragic start to the year and if it continues like this, it will be a tragic record, says Diamant Salihu.
Several murder patrols
Drugs are a common denominator in many of the ongoing conflicts.
Diamant Salihu also says that groups in different parts of the country help each other - among other things to access their enemies.
A group in Stockholm can get help from a "friends association" in Gothenburg or Malmö
- Then a torpedo comes to Stockholm and shoots dead a person you yourself have difficulty accessing.
One exchanges murder.
There are even murder patrols that are willing to commit murder for a fee or just to show their loyalty.
Sweden's most violent cities
Most of the shootings have taken place in the Stockholm area, but also in the Linköping area, the severe violence has increased.
- It is one of Sweden's most violent cities in the last year with six fatal shootings, says Diamant Salihu.
Detective Commissioner and gang expert Gunnar Appelgren has previously told SVT that in some places there is a power vacuum where the terrorist balance has been put out of play.
This after several leading figures in the criminal environment have been prosecuted.
- There will be a power vacuum and then there will be conflicts.
You may have conflicts that started six or seven years ago that have developed into vengeance.
You are not satisfied until you have killed all your rivals, says Diamant Salihu.
