Aug. 6 (UPI) -- A woman in Arizona is charged with attempting to kill her husband by poisoning his coffee.
Melody Felicano Johnson, 39, was arraigned on Friday on charges of attempt to commit first-degree murder, attempt to commit aggravated assault-serious injury and adding poison or a harmful substance to food or drink, KVOA in Tucson reported.
Johnson pleaded not guilty. She is being held in Pima County Jail on a $250,000 bond, according to KOLD.
Roby Johnson, Melody Johnson's husband, alleges that he began noticing that his coffee tasted strange when he and his wife were stationed in Germany in March. Roby Johnson serves in the U.S. Air Force.
After a few weeks, he used pool testing strips to test the coffee and found that it contained high levels of chlorine.
Roby Johnson then installed hidden cameras to catch his wife putting something into his coffee, CNN reported.
In June the couple returned to Tucson in temporary housing. He set up cameras there as well. The footage allegedly captured her putting bleach into a container and pouring it into the coffee maker.
Roby Johnson shared the footage with the Tucson Police. He believes his wife was trying to kill him to collect "death benefits."
According to court documents, a complaint was filed against Melody Johnson on July 18. She has been assigned a public defender.
