A California man says that his wife was poisoning his drinks with the drain-cleaning product Drano and that he caught her on video doing it, as reported by Fox News.

A dermatologist appeared in court April 18, 2023, to speak on allegations that she poisoned her husband, a radiologist, with tea that contained Drano.

Dr. Yue “Emily” Yu’s lawyer says that the woman’s husband has actually suffered injuries from gastroesophageal reflux disease, also known as acid reflux.

“As you know Drano is a caustic substance. You’d have severe injuries,” said attorney Scott Simmons. “His injuries are consistent with a benign condition called GERD or acid reflux,” he told reporters.

Husband Jack Chen alleges that in April 2022 he noticed his tea and lemonade tasted strange and he began to feel sick. Chen developed two stomach ulcers, gastritis, and inflammation of his esophagus, according to the report.

Chen then installed three cameras in his kitchen that allegedly caught Yu putting Drano in his drinks on three separate occasions in July 2022.

The man also said his wife and her mother emotionally and verbally abused him and his children. Chen claimed in his statements that his wife would demand massages and if he refused, “she stepped my head until I did.”

Yu’s lawyer did not deny the Drano was being put in drinks, but offered a different explanation for the matter.

“They had a big ant problem in the kitchen. Jack Chen tells her to put the Drano into this lemonade or tea in order to bait and kill the ants,” Simmons said.

“He then sets up what he calls spy cameras to capture her pouring the Drano into the cup, then falsely accuses her of trying to poison him,” the attorney added.

Simmons told Fox News that Mr. Chen set up his wife in order to strengthen his claims of custody over their two children and gain an upper hand in divorce proceedings.

In August 2022, the month following his claims against his wife, Chen filed for a restraining order, divorce, and sole custody of the children, all on the same day.

“The so-called smoking gun of the video is not a smoking gun at all,” Simmons declared.

Yu could face up to eight years in prison if convicted, according to the Orange County District Attorney’s Office. She was originally released on $30,000 bond.

Her arraignment for three felony counts of poisoning and one felony count of domestic battery with corporal injury was postponed for a month.
