MACOMB TOWNSHIP, Mich. -- The Macomb County medical examiner said a 42-year-old woman found dead last month in her blood-splattered Macomb County condo with no signs of injury to her body died after drinking too much water.

But the source of the blood remains a mystery.

Police are awaiting tests to find out whether it was Andrea Jean Bean's blood on some walls of the home. There was no blood on Bean or the bed where she lay and no signs of trauma to her body.

Police said significant amounts of blood were smeared all over the bedroom, kitchen and hallway.

The Macomb County Medical Examiner's report concludes that the divorced mother of three died of very low sodium levels. The water forced an electrolyte imbalance, which triggered a seizure and led to her death.

Death by water is rare, but it claimed the life of a 28-year-old California woman after she participated in a radio-station sponsored "Hold Your Water" competition.

Spitz said she had a psychological condition that led her to drink a fatal amount of water.

Bean's father, John Collier, told Local 4 that his daughter suffered from psychogenic polydipsia. Something, he said, she had been dealing with for the past three year.

"She just didn't sense her own perils," Collier said.

Collier said his daughter had a compulsion to drink water and that she never grasped the concept that something bad would happen to her as a result of it. He also said Bean has been in the hospital for excessive water drinking three times in the past.

Collier said he believes his daughter may have drunk as much as two gallons of water in too short of a time before it led to her death.

Collier said he and his wife had tried to gain legal guardianship of their mentally ill daughter, but were denied by the mental health community. Collier said he feels his family did not receive the kind of treatment they should have.

"I am angry. I am unbelievably angry," said Collier. "This is a life that was lost that shouldn't have been."

Medical Examiner Daniel Spitz said he considered the death an accident. Bean has been hospitalized for mental illness at least 17 times and was released from a mental facility just two weeks before her death, Bean's family told the Macomb Daily newspaper.

A nanny and Bean's children, ages 2, 7, and 9 found Bean's body July 29 in her Macomb Township condo about 25 miles north of Detroit.
