A 70-year-old woman from Queens, New York, was recently arrested after her husband caught her lacing his coffee with boric acid.
Robert Baron first noticed that the food his wife cooked for him tasted funny back in September 0f last year. He also started feeling sick after meals, and on some occasion he would get so tired that he slept for 15 hours at a time.
Suspecting that something fishy was going on, the 63-year-old man installed a small surveillance camera in the kitchen, without telling his wife of 11 years, Suncha Tinevra. Thatâs how he caught his partner lacing his coffee with a chemical used to kill cockroaches.

It turns out that the elderly woman had dumped boric acid into her husbandâs coffee, which she later admitted to, adding that it hadnât been the first time.
âIâve done this two or three times, I donât remember when, just when Iâm angry,â Suncha Tinevra told police. âI just wanted to teach him a lesson.â
The 70-year-old woman was released last Friday without bail, but with an order of protection forbidding her to go near her husband.
Boric acid is a white powder that is widely used in various fields. Itâs sometimes used as an antiseptic to treat light burns or cuts, but also as an insecticide against cockroaches, ants and other insects. According to an affidavit from a case similar to the one presented above, a tablespoon of boric acid is enough to kill a 150-pound man.
