Sammamish grandmother charged 6-months after Jeep she was driving plowed through family home killing two

SAMMAMISH, Wash. -- The woman who drove her Jeep through her home on Lake Sammamish, killing her husband and son-in-law and seriously injuring her daughter in May has been formally charged by prosecutors.

Carol Sue Fedigan, 68, now faces two counts of vehicular homicide and one count of vehicular assault.


Fedigan also faces a reckless endangerment charge because prosecutors said she was driving with her 3-year-old grandson on her lap.

Court documents say Fedigan’s blood alcohol content was .091 and traces of Ambien were also present at the time of the crash.

“Alcohol interacts with Ambien and increases impairment,” wrote prosecutors.  “Ambien can cause confusion and psychomotor impairment, augmenting the effects of alcohol.”

Prosecutors said the amount of Ambien in Fedigan’s system was too high for any prescribed dose that might have been taken the previous night before bed.

Detectives at the time said Fedigan was trying to re-park a new Jeep outside the family home, with her 3-year-old grandson on her lap.

The child was uninjured.

Three family members were inside the home. Fedigan's 70-year-old husband, David Walker, died at the scene; her 40-year-old son-in-law, Sean Berry, died later at Harborview. Her daughter, Megan Berry, was critically injured.

Megan Berry is a fifth-grade  teacher at Kenmore Elementary.

Concerns over the admissibility in court of recently collected blood alcohol samples kept prosecutors from moving forward with this particular case for more than 6 months.

Court documents say investigators learned Fedigan had a ‘significant alcohol problem’ prior to the tragedy and that her family held several unsuccessful interventions in an attempt to get her into rehab.

Fedigan's arraignment is set for December 18th at the King County Courthouse.
