(NewsNation) — The woman caught on camera trying to systematically poison her husband will serve three years’ probation and undergo a mental health evaluation.

Melody Felicano Johnson accepted a plea agreement and admitted to poisoning her U.S. Air Force husband’s food and drink, including spiking his coffee with bleach.

Airman Roby Johnson, however, suspected something was wrong. He planted cameras in the couple’s kitchen and caught her on video. Johnson believes his wife was trying to kill him to collect death benefits.

According to court documents, Roby Johnson noticed the odd-tasting coffee in March of 2023 when the couple was living in Germany. He pretended to drink the coffee.

He set up cameras in their kitchen once they moved to Tucson, Arizona, last summer. After tests of the coffee showed traces of chlorine, he notified police.

Melody Johnson was arrested in July and jailed. Roby Johnson asked the judge for leniency for his wife because they have a child together.
