Monday, KULR 8 obtained court documents which led Billings Police to a suspect in the murder of 67-year-old Cynthia Anna Cook.

Police arrested Jonah Bergman, Saturday afternoon, after talking to him in the City Brew parking lot, located on Main Street.

Court documents state there was blood on Bergman's shirt. When police asked him about it he told officers, "I just stabbed and killed my mother." Officers then placed Bergman in handcuffs, put him in a patrol car and went to conduct a welfare check on Cook at Bergman's home on Claim Jumper Lane.

At Bergman's home, officers said no one answered the door so they began to look through the windows. 

In the backyard, one officer observed what appeared to be a drop of red liquid on the deck. He then looked through a window where blinds were partly open and saw a light on in the bedroom. The officer said he saw a bloody knife on the floor and a woman lying face down with a large amount of blood on her.

Officers began to clear the house. Once in the bedroom, police say it was evident Cook was stabbed multiple times. She was pronounced dead at the scene.

Later, the woman was identified as Bergman's mother.

No other victims were found inside the home. 

Police then spoke with neighbors and were told Bergman was possibly bipolar or schizophrenic and that only he and his mother lived at the house.

Bergman is being held at the Yellowstone County Detention Facility.

Cynthia Cook's family has set up a GoFundMe page to help cover costs of the memorial. You can find the page here.
