The bodies of the three were found near Uddevalla’s hospital. One was in a car in a parking lot while the two others lay outside the car.

A jogger discovered the body in the car, a man, just before 7am on Saturday morning and police found the other two when they arrived on the scene.

“We have blocked off the area and police are on their way to begin, among other things, knocking on doors in the vicinity,” said Christer Fuxborg, a police spokesperson.

Medical examiners also arrived on Saturday morning to investigate.

A reporter from the TT news agency said grieving people had come to the parking lot and that one woman tried to get past the police barricade, but was stopped.

The dead have not yet been identified and police have not released information on the gender of the two found outside of the car. According to P4 Väst, the local public radio station, the victims were two men and a woman, all in their 20s. The woman was reported to be in a relationship with one of the men. It is known that the car was not registered in the name of any of the deceased.

Police are also not releasing information on if a weapon was found or when the deaths occurred.

One person told the Göteborgs-Posten newspaper that he heard something that he believed were firecrackers at around four o’clock Saturday morning.

“Then a car drove away at high speed,” he said.

A woman speaking to the Borås Tidning newspaper said no one in the area was allowed to leave the vicinity. She had also heard small explosions during the night.

“In the morning I saw two bodies outside the house. It was obvious that the two were dead,” she told the paper.

Police do not yet have any suspects in the case.
