Summary
Prosecutors say Kouri Richins made Eric a Moscow Mule on March 4, 2022. His favorite drink. From his wife's hands.
Fentanyl inside, according to the charges. Dead within hours.
This is what the caretaker killer looks like. Not violence. Not rage. Just a drink, made with love, handed over with a smile.
Stacey Castor did the same thing to two husbands in Syracuse. Antifreeze in their beverages. Michael Wallace in 2000. David Castor in 2005. Both times she played the devoted wife — bringing them drinks, nursing them, watching them die.
She was the reason they were dying.
When investigators got close, Stacey tried to add a third victim: her own daughter Ashley. Drugged her with vodka and pills, typed a fake suicide confession, left her to die with the blame for both murders.
Ashley survived. The forensic evidence proved Stacey typed the confession. The judge gave her fifty-one years.
Prosecutors allege Kouri Richins follows the same pattern. The devoted wife. The favorite drink. The poison hidden inside. According to testimony, Eric got sick on Valentine's Day 2022 — one month before his death.
The caretaker doesn't look like a killer. She looks like exactly what you need when you're tired, when you're thirsty, when you want to relax at home with your wife.
That's the mask. That's the weapon.
