LATEST Aug. 31, 9:30 a.m. A victim in the dish soap poisoning incident in San Mateo has been identified. 

Gertrude Elizabeth Murison Maxwell, 93, died after allegedly being poisoned with dish soap that was mistaken for juice, reports KRON-TV. 

The victim's daughter, Marcia Cutchin, told the outlet that her mother was taken to hospital in an ambulance on Sunday, suffering from “severe blistering of her mouth and throat and esophagus” from the consumption of the "alkaline cleaning solution." Maxwell was a mother to eight children and a grandmother to 20.

Aug. 10, 11 a.m. San Mateo police are investigating the death of a 93-year-old woman at a care home facility after she was possibly poisoned with dish soap.

The incident occurred on Sunday evening at the Atria Hillsdale care home facility in San Mateo, and left two other residents in hospital, SMPD said in a statement.

"SMPD began a comprehensive investigation and learned three home care residents were hospitalized after ingesting toxic chemicals," the statement read. "Tragically, one of the three residents, a 93-year-old female, was pronounced deceased at a local hospital."

Police did not provide additional information on the current condition of the two injured victims. The care facility claims that the dishwashing fluid was mistaken for juice.

"We can confirm three of our residents were recently transported to the hospital after mistakenly being served dishwashing liquid as drinking juice. We have been working with local authorities, who have informed us that one resident passed away," a Atria Hillsdale spokesperson told KPIX in a statement, adding that they are conducting an internal investigation alongside helping authorities.

The facility, located on East Hillsdale Blvd, approximately 20 miles south of San Francisco, costs on average around $4,500 a month and has a four-star rating on Family Assets, a website that connects families with care providers. SFGATE reached out to Alta Hillsdale for further comment but had not heard back at time of publication.

San Mateo police have asked that any witnesses who may have any additional information contact Sgt. Detective Paul Pak at (650) 522-7660 or pak@cityofsanmateo.org.
