Calif. grandmother charged with drowning grandson, 4, in bathtub

FAIRFIELD, Calif. -- Prosecutors have charged a northern California grandmother with murder in connection with drowning her 4-year-old grandson in a bathtub.

If convicted, 51-year-old Dawn Diana Raines-Hewes could face 25 years to life in state prison.

The Los Angeles Times reports Thursday that police say Raines-Hewes was arrested Tuesday morning when police say neighbors saw her run screaming from her house, then found her grandson unconscious inside.

In a statement Wednesday, Fairfield police said that during the investigation, Raines-Hewes admitted to the intentional act of drowning the child. Two other grandchildren, a 1-year-old girl and a 6-year-old girl, were also under the grandmother's care. Police say they were not harmed.

A motive has not been released. She remains jailed without bail.

It was not clear Thursday if she has an attorney. But several extended relatives called her a loving and caring woman.
