Authorities said Mrs Knarr walked behind Mr Knarr who was sitting in the dining room of their Bozeman home and shot him in the back of the head before shooting their son Daniel in the chest.

She then called 911 and hung up before sitting down and shooting herself, authorities said. 

Sheriff Brian Gootkin said investigators may never know the reason for the shootings.

Family members who spoke with Gootkin indicated that Mrs Knarr had been battling postpartum depression since the birth of her son last fall.

'It was emotional and tough but every single person that I talked to was strong and every one of them understood what happened,' Gootkin told NBC Montana.
