A woman who stabbed a man to death this week in Des Moines is not going to face criminal charges.

25 year old Tyshar Mosley of Des Moines shared an apartment in the 1900 block of 7th street with 34 year old Amyn Dewayne Brown. There was an argument early Thursday morning, and soon after Brown was found by police at the apartment, dead of stab wounds.

Police took Mosley in for questioning as a person of interest. Sgt. Daniel Blom says police have completed their investigation, and after reviewing the evidence and statements, Mosley is not going to be charged with a crime.

Blom says they've determined she was acting in self defense by protecting herself and her children during a fight with Brown.
