• The man suspected something was wrong when his meals began to taste 'funny' 
  • Detectives recovered a bottle that contained boric acid
  • The woman told police she did this "two or three times" as she was angry with her husband

A 70-year-old woman from Queens, New York, has been arrested for trying to poison her husband's coffee with a roach killer.

According to a statement from Queens District Attorney Melinda Katz's office, Suncha Tinerva was caught on camera adding the insecticide to her husband's morning coffee, ABC News reported.

"Tinerva retrieved the bottle from the cabinet under the sink and allegedly spiked her husband's coffee on two or three occasions. On Jan. 14, 2021, at approximately 10:40 p.m, detectives recovered a bottle with a red cap and yellow label from the spot under the sink," the office said.

Further tests revealed that the bottle contained 100% boric acid – a substance used to kill ants and roaches. People who consume boric acid can have nausea, vomiting, stomach aches, diarrhea, cough, sore throat and nose bleeds. Tinerva's husband, however, survived despite feeling sick, said the report.

"I've done this two or three times. I don't remember when — just when I'm angry. I just wanted to teach him a lesson," she told the police, the New York Post reported.

Tinerva married Rober Baron 11 years ago. The 63-year-old man told police that he sometimes felt unwell after meals and would feel overly tired, sleeping for 15 hours at times. He grew suspicious and installed a camera in the kitchen. He said he found Tinevra adding poison into his coffee on Jan. 12.

He immediately alerted the police. Tinerva was arrested Thursday. Police also seized the coffee pot, boric acid and tainted coffee as part of their investigation.

Tinerva was released Friday without bail, but with an order of protection barring contact with her husband. She has been charged with attempted assault in the second degree, reckless endangerment in the second degree and criminal possession of a weapon in the fourth degree.
