BERLIN (AP) – A man suspected of killing six relatives in a shooting in southwestern Germany was ordered held in custody on Saturday pending a possible indictment, authorities said.

The 26-year-old suspect was arrested at the scene of Friday’s shooting, a building containing a bar in the small town of Rot am See, after calling police to inform them that he had shot and killed several people.

The bodies found at the scene were those of the suspect’s parents, his step-siblings and an aunt and uncle. A judge ordered him kept in custody on suspicion of six counts of murder and two of attempted murder, police and prosecutors said in a brief statement Saturday.

Two people were wounded in the shooting – a man who was still in a critical condition on Saturday and a woman who was slightly hurt. Police told news agency dpa earlier Saturday that they still have no word on a possible motive.

The suspect lived with his father in an apartment above the bar, which his father ran.

Police have said that the suspect had a license to own firearms as a shooting club member and had no criminal record. They believe he used a semi-automatic pistol.
