It's been a bloody month in the Twin Cities.
It's the 26th homicide in the city this year.
A 26-year-old man was found shot dead at the park earlier this week.
Three of the victims were his family members.
The mass killing happened at a business in Mandan, central North Dakota.
The pair were found dead from gunshot wounds at an apartment on Saturday.
The woman said the victim was her friend and hopes his family can forgive her.
