A Virginia woman reportedly tried to poison her coworkers by adding cleaning solution to the work place's coffee machine.
Mayda E. Rivera-Juarez, a 32-year-old worker at the small shipping company JAS Forwarding, allegedly poured kitchen and glass cleaning products into the break room's Keurig machine over a number of weeks, according to WJLA.
"The employees at this place had been getting sick, didn’t quite know what was going on," Loudoun County Sheriff Mike Chapman told WJLA. "When she was coming in to get terminated, some of this came to light."
Employees suffered from digestive problems as well as diarrhea, according to The Huffington Post, and the company's boss had a feeling that a coworker could be responsible for the wide-spread contamination.
Coworkers immediately thought that Rivera-Juarez was the mastermind behind the contamination, according to WTOP. Many had previously filed complaints about her, saying that she never saw eye-to-eye with the rest of the office and had a consistently disgruntled attitude. Details remain scarce, however, and although Rivera-Juarez admitted to poisoning her co-workers, she did not give a motive for doing so.
She is not the only worker to have allegedly poisoned her office mates, according to the Independent.
In early 2016, Melissa Swift, an employee at a care home in the U.K., was accused of pouring bleach into her colleagues' mugs when they weren't looking. Smith was sentenced to eight years in prison.
Around the same time, a 23-year-old New York woman was found guilty of fatally poisoning her boss.
In both stories, the women's motives also remain unknown.
Rivera-Juarez was arrested and charged with felony assault, according to The Huffington Post. She is currently in jail with no set bond.
The poisoned coworkers have since made a full recovery.
