MISSOULA, Mont. -

 Authorities say a 17-year-old boy who was shot and killed over the weekend by a Missoula man who claimed the teen had broken into his garage was a foreign exchange student from Germany.

Police in Missoula have arrested a 29-year-old man on suspicion of deliberate homicide in the death of Diren Dede of Hamburg, Germany. Dede was a junior at Big Sky High School in Missoula.

Officers responded to the reported shooting just before 12:30 a.m. Sunday.

Markus Kaarma told officers he found an intruder in his garage after an alarm went off, and he shot him with a shotgun. Dede later died of his injuries.

Sgt. Travis Welsh says it will be up to the county attorney's office to determine if Kaarma will face criminal charges. Welsh said officers would not arrest someone without probable cause that a crime had been committed.

The shooting is still under investigation.
