MISSOULA, Mont. -

The man who shot and killed a German exchange student will be arraigned in Missoula County District Court Wednesday.

Markus Kaarma's defense team says Kaarma will plead not not guilty to a deliberate homicide charge.

The 29-year-old Missoula resident claims he was scared for his life when German exchange student Diren Dede, 17, entered his garage early one morning last month. Court documents say Dede was looking for something to drink, and add that Kaarma was agitated after previous burglaries.

Prosecutors say Kaarma told police he didn't hear or say anything before firing into a dark garage.

Kaarma's defense team asked for a judge substitution in the case. Tuesday, Missoula County District Court Judge Ed McLean was assigned.

Kaarma is scheduled to be arraigned at 10:30 a.m. Wednesday.
