Woman Gets 3 Years in Prison for Adding Windex to Coworkers’ Coffee

The woman charged with poisoning her co-workers’ coffee at a Sterling office last year was sentenced to serve three and a half years in prison.

Mayda Edith Rivera Juarez, 33, of Sterling, appeared before Circuit Court Judge Jeanette A. Irby on Tuesday for sentencing on one count of adulteration of food with intent to injure or kill.  She pleaded guilty to the offense in February.

According to evidence in the case, beginning in January 2016, her co-workers began experiencing stomach pain, vomiting, nausea, and other physical ailments. One victim noticed that his symptoms occurred soon after drinking coffee from the office breakroom. In October 2016, the victim reported his suspicions that someone was tampering with the coffee machine to his supervisor.  The supervisor reviewed security camera footage in the breakroom and observed Rivera Juarez pouring Windex into the water reservoir of the office coffee maker. She was immediately fired.

In a statement to investigator, Rivera Juarez said she put Windex in the coffee machine to make her supervisor sick and had also put Ajax dish soap in the coffee machine and that she had had poured Ajax directly into her supervisor’s coffee cup.

Irby imposed a sentence of three years and six months in the Virginia Department of Corrections. Upon her release, Rivera Juarez will be placed on three years of supervised probation.
