An Arizona woman is behind bars after allegedly attempting to kill her husband by adding bleach to his coffee over a period of several months.

As reported by the regional outlet KVOA last week, Melody Johnson is accused of initiating the alleged poisoning attempt in March of this year. At that time, Johnson and her husband, who was not named in the initial reports but was identified by CNN as Roby Johnson, were in Germany. According to court documents, Roby is a member of the United States Air Force and was stationed in the country at that time.

The couple shares a child but are currently going through a divorce, according to the documents. In March, Roby stated that he noticed his coffee had begun to taste "bad." Several weeks later, he purchased pool chemical test strips, eventually using them on the faucet water and the water in the coffee maker. Allegedly, the latter showed "high levels of chlorine," prompting him to set up a camera in May. Supposedly, footage captured Melody pouring a liquid into the coffee maker, leading Roby to decide to only pretend to drink the coffee from that point onward.

By early July, both had returned to the United States. Additional footage allegedly captured by Roby showed Melody pouring bleach into a container and then pouring it into the coffee maker.

According to KOLD, Melody was later arrested. Furthermore, a search resulted in the police finding a liquid in the coffee maker "that smelled like bleach," as well as a container beneath her bathroom sink that also smelled like bleach.

According to online jail records, Johnson is currently in the custody of the Pima County Adult Detention Center. At the time of writing, no bond amount had been listed. Court documents argue that Melody is a potential flight risk.

Police state that Roby believes his wife wanted to kill him in order to "receive death benefits." Specific accusations against Melody include attempted first-degree homicide, attempted aggravated assault, and adding poison or harmful substance to food or drink.
