OC judge dismisses indictment against Mission Viejo doctor in Drano case

An Orange County Superior Court judge dismissed the indictment against a Mission Viejo dermatologist accused of poisoning her physician husband by putting Drano in his tea, ruling the process used to obtain the charges was fundamentally flawed, ABC7 Los Angeles reported Saturday.

The dismissal is a significant setback for the Orange County District Attorney's Office in a high-profile poisoning case, though prosecutors said they will re-file charges — signaling the legal fight over the Mission Viejo physician is far from over.

Judge Patrick Donahue of Orange County Superior Court dismissed the indictment against Dr. Yue "Emily" Yu after examining the proceedings that produced the charges, according to ABC7 Los Angeles. The judge determined those proceedings were fundamentally flawed.

Yu, a dermatologist based in Mission Viejo, is accused of putting Drano drain cleaner in her husband's tea; her husband is also a physician. The case has faced repeated legal complications since early 2026, when Donahue allowed prosecutors to file a revised indictment carrying added charges of attempted poisoning.

Defense attorney Simmons praised the outcome. "We are grateful that the court closely examined the proceedings that produced this charge and recognized that the process by which the indictment was obtained was fundamentally flawed," Simmons said. Simmons also said: "Emily Yu should not have been indicted. From the outset, Emily has maintained that she did nothing wrong and has placed her faith in a fair and impartial legal process."

The Orange County District Attorney's Office vowed to press forward. "We are re-filing this case. We believe in the strength of the evidence in this case, and in the professional conduct of our prosecutors. We will continue to litigate this in a court of law as we pursue justice for an individual who was being methodically poisoned by his wife, a licensed medical professional whose intent was to inflict pain on him," said Kimberly Edds, a spokeswoman for the office, according to ABC7 Los Angeles.

Simmons described the toll the prolonged case has taken on his client. "She really wants to move on with her life. She hasn't practiced medicine this whole time. It's really a bummer for her and she hasn't been able to see her children," Simmons said.

With the Orange County District Attorney's Office committed to re-filing, the case against the Mission Viejo dermatologist is expected to return to an Orange County courtroom, keeping it among the most closely watched criminal proceedings in the county.
