An Arizona Woman Was Divorcing Her US Air Force Husband. Then, She Began Poisoning His Morning Coffee.

An Arizona woman has pleaded guilty after she was accused of trying to kill her husband by poisoning his coffee, authorities said.

A grand jury in Tucson recently indicted Melody Felicano Johnson on charges of attempting to commit first-degree murder, attempting to commit aggravated assault, and adding poison to food or drink, KVOA reported.

According to court documents obtained by the station, Johnson began to daily poison the coffee of her husband, Roby Johnson, beginning in March 2023, when they were still living in Germany, where he was stationed with the US Air Force.

The documents state the husband began to notice his coffee had a foul taste, so he tested it with pool strips and found it contained high levels of chlorine.

He then set up hidden cameras and, according to the legal documents, observed his wife pour something into the coffeemaker, CNN reported.

The estranged couple, who were going through a divorce but continued living together with their child, returned to Arizona in June 2023.

Roby pretended to continue to consume the coffee but again set up cameras, which, court documents state, captured footage of his wife “Melody take bleach, pour it into a container and then walk over and pour it into the coffee maker.”

According to investigators, Roby took the footage to police, and he believes Melody “was trying to kill him to collect death benefits.”

On April 8, Johnson entered a guilty plea to two counts of adding poison or a harmful substance to food or drink, officials said. By agreeing to the plea deal, prosecutors dropped the attempted murder charge.

Prosecutors recommended she serve two years in prison, but she could serve as much as four years. After being released from prison, she will be placed on probation for up to three years.

A judge will sentence Johnson on May 10.
