A Michigan mother who butchered her three young children in the woods last Monday before committing suicide outside her boyfriend's home used a fake doctor's note to get them out of school, police say.

Abrianne Moore, 28, turned up at a her daughters' school in Kent County last week, telling teachers that she needed to take Alaina Rau, 2, Cassidy Rodery, 6, and Kyrie Rodery, 8, to a doctor's appointment.

However Moore secretly had other plans.

Instead, she drove the girls out to a wooded area behind their great-grandparents' home and lured them from the car one-by-one, and executed each of them with a hunting rifle.

She then loaded the children's lifeless bodies back into her car, drove to her boyfriend's home and shot herself. The boyfriend and father of the youngest daughter discovered the gruesome scene an hour and a half later.

The note she handed to school administrators was a forgery, the Kent County Sheriff's Office revealed on Sunday.

'We don't know what was going through her head, she didn't leave a suicide note or anything like that,' Kent County Sheriff Michelle LaJoye-Young told MLive on Wednesday.

Investigators believe Moore committed triple murder-suicide because she was suffering from mental illness.

Mom appears to have been struggling with pretty substantial mental health issues,' LaJoye-Young said.

'She had some postings on Facebook and things like that that lead to believe she was paranoid and thought that the kids were in jeopardy somehow. We suspect that led to the events this day.'

Last September, Moore's former social worker filed a petition to the Newaygo County Probate Court, suggesting she be admitted to a mental hospital.

'Aubrianne is keeping her kids home from school because the television told her there would be a school bus accident today,' the social worker wrote in her report.

'Aubrianne stays awake at night believing people will break into her home. Aubrianne is not eating believing food is being poisoned,' WYFF reported.

I believe the individual has mental illness and as a result of that mental illness the individual can reasonably be expected within the near future to intentionally or unintentionally seriously physically injure self or others.'

Moore was diagnosed with 'unspecified schizophrenia' and 'psychosis' in September 2018 and was involuntarily hospitalized for 10 days, according to NewayGo County Probate Court records.

LaJoye-Young said this case has been one of the most difficult that she's had to handle in her 29 years in law enforcement.

'This is one of the hardest cases I've ever heard about. This is a very difficult case,' she said on Wednesday. 'Our investigators are feeling it. It's heartbreaking that something like this happened in our community.

'I'm heartbroken for the family and for everybody involved and the community at large, because this is not something that's easy for us to not wonder what could have been done differently, what could we have done to help.'

A GoFundMe campaign set up by Moore's brother, Robert Graham, has raised more than $6,300 as of Thursday morning.

Graham said any money left over after funeral costs are covered will be used 'for legal purposes (trying to figure out how Aubrianne was neglected by doctors and treated to a lesser degree of help than what she needed)'.
