WOONSOCKET, S.D. -

A South Dakota man accused of killing a woman last month has been indicted on alternate counts of murder and manslaughter.
    
The South Dakota attorney general's office says a Sanborn County ground jury on Monday indicted 33-year-old Woonsocket resident Matthew Novak on alternate counts of first-degree murder, second-degree murder and first-degree manslaughter.
    
Law enforcement authorities say Novak killed 25-year-old Jennifer Gibson at their Woonsocket home on or about Aug. 31. Few details of the killing have been released.
    
Authorities arrested Novak at the home on Aug. 31 after the incident that prompted authorities to lock down a nearby school.
    
It wasn't immediately clear if Novak has an attorney who could comment on his behalf. Novak requested a court-appointed attorney during a previous court hearing.
