Police are investigating the Oregon woman's death as a homicide, local NBC News affiliate KGW-TV reported.

They believe her body was moved to the barn after she died from blunt force trauma at a different location.

Speaks left behind three children – a seven-year old girl and two boys, 12 and 13.

She lost contact with her family in March. Relatives said the mother had been struggling with addiction on and off for years.

Speaks' family has started a GoFundMe to help pay for her funeral expenses.

"Her children have made it clear that they would like to keep a piece of her with them, but also have a place to visit where her name and life will be engraved and never forgotten," the campaign's website said.

"We're hoping that we can at least give them that."

The GoFundMe has reached $4,550 of its $5,000 goal.
