The daughter of the man police hold responsible for Sunday's murder-suicide in a Montana log cabin says her father was in denial about having mental health problems.

Starla Shannon says she's convinced her father, Augustine "Mike" Bournes, had an undiagnosed mental illness that turned dangerous.

Police say Bournes killed his wife and their three young children before setting fire to their cabin and killing himself.

Shannon defended her dad Wednesday as someone who loved his family even though he had cut off communication.

Interviews with Bournes' daughter, ex-wife, acquaintances and authorities in rural, southwestern Montana are helping tell the story of a man with an anti-government streak who killed his family and himself after telling someone that his wife, Arie Arlynn Lee, had been "mocking and riding him all day."
