“Yes, I think that we can start with that theory,” Henrik said. “In any case, it was an incredibly precise incision around the victim’s neck, which means that it was carried out by someone who was comfortable using a knife. The murder seems well-planned. There were no other stab wounds to the body. The goal was to kill, plain and simple.”

Everyone sat quietly for a moment.

“Career criminal, in other words,” Gunnar said. “And the victim wasn’t in a gang?”

“There’s nothing to suggest that, no,” said Ola. “But we do know that he was fairly politically active. Left-wing activist, maybe.”

“Extreme left-wing?” Per asked.

“I don’t know,” Ola said. “I’ll check him out thoroughly. We’ve confiscated his computer.”

“Check it immediately after this meeting,” Gunnar said.

“I will,” Ola replied.

“Do we know if he was still using drugs?” Per asked.

“Unfortunately not,” Henrik said. “But we’ll have to check that out, too. It’s very possible that he was still using, that the murder was a drug-related dispute of some sort...in the underworld, that is.”

“Or a debt,” Mia said. “Maybe he owed someone money, couldn’t finance his drug problem.”

“Henrik and Mia,” Gunnar said. “You continue to survey the territory around the narcotics trade in town, maybe revisit the people you’ve already talked to. Check the criminal network.”

“As I’ve understood it,” Henrik said, “Gavril Bolanaki controlled a large piece of the market. But otherwise it’s primarily the motorcycle gangs that are dominant here.”

“That’s true,” Gunnar said. “They’ve steadily built up influence based on fear and violence, and they’re using that to control the narcotics trade and to employ extortion against business leaders within, for example, the hospitality industry. But there are many more networks than just them.”

He quickly counted them: Red & White Crew, Black Cobra, M-16, Gypsy Bloods, Asir, the Berga Gang, Berga Boys, Outlaws and Bandidos.

“These networks primarily attack each other because they are competing for the same market. We’ve seen this numerous times. In March of 2011, a man was stabbed in an apartment on Bråbogatan. Later the same evening, downtown, another man was shot in the leg. Four men were arrested, but they were released due to lack of evidence. One of them was said to be the leader of the Black Cobras. In June that same year, gunshots were fired outside the Deli pub, and that was Black Cobras attacking members of the Outlaws. The district court acquitted all of the defendants, but on appeal one of the men connected to the Black Cobras was sentenced to five years in prison for attempted murder.”

Gunnar held his finger up in the air.
