A 22-year-old woman is charged with second-degree murder in the death of her fiancé at a home in Rolla.

Meghan Werner of Rolla is also charged with armed criminal action. She is jailed on $1 million bond.

Police say 22-year-old Curt Marzlof of Monroe, Wisconsin, was fatally shot about 5:45 a.m. Saturday. Werner told authorities that Marzlof committed suicide.

Police say they determined the couple had been involved in a physical altercation. Police also cited evidence that Marzlof's death was not a suicide. Details about that evidence have not been released.
