Medical examiners have ruled an elderly Bothell woman’s death on Oct. 27 a homicide.

Lila J. Donaldson, 81, died of a blunt impact to the head, the Snohomish County Medical Examiner’s office determined Tuesday.

Donaldson was found suffering from severe traumatic injuries and later died at the scene more than two weeks ago.

The woman’s 42-year-old daughter, Terie Sue Davidson, was arrested on Oct. 27 and later charged with murder.

The Bothell Police Department received a 911 call at approximately 5 a.m. Oct. 27 from the daughter who requested some medical assistance at a mobile home where she resides located in the 3300 block of 228th St. S.E. in Bothell.

Officers contacted the woman outside her front door. Due to some concerning statements and behaviors, the officers determined they needed to check the welfare of anyone inside the residence.

The officers found the woman’s mother inside, who was suffering from severe traumatic injuries. Medics and aid responded to treat the woman, however she died while still at the scene.

The daughter was taken into custody and as of Monday was in the hospital for undisclosed medical issues, said Langford.

Detectives searched the home following the incident.
