93-year-old woman dead after seniors served dishwashing liquid at San Mateo senior living facility

SAN MATEO, Calif. (KGO) -- A 93-year-old woman was pronounced dead after police confirmed she ingested toxic chemicals at Atria senior living facility in San Mateo.

"I'm concerned that the level of care is not adequate because issues like this shouldn't happen. This is very major since it resulted in a death," said June Lee, Hillsborough resident.

We met Lee outside of the facility. She was planning to register her husband into this home this week.

"I will not consider this assisted living facility any longer," said Lee, adding, "Did they mention anything about the incident? No, the sales director did not mention the incident."

The incident took place on Sunday night. Atria's team said two other residents were also hospitalized. In their statement, they revealed what the toxic chemical was: "We can confirm three of our residents were recently transported to the hospital after mistakenly being served dishwashing liquid as drinking juice."

San Mateo's District Attorney Steve Wagstaffe confirmed San Mateo police brought this case to his attention Monday morning.

"At least at this point anyway, we concluded that whatever occurred we don't think at this point, doesn't mean we rule anything out, but at this point we don't think it was an intentional act by someone trying to harm people," said Wagstaffe.

If the current evident points to this not being intentional, then what happened? DA Wasgstaffe said negligence hasn't been ruled out.

"If it was people not being careful with the liquids and people suffered harm or death by it, that would be of course could be a very significant lawsuit out of it. Technically there is a thing in the criminal law called criminal negligence," said Wagstaffe.

This facility also confirmed they are conducting an internal investigation and the employees involved have been suspended for the time being.
