Utah mom and grief book author Kouri Richins is suing the estate of her late husband, whom she allegedly killed — claiming she deserves money and physical assets outlined in their prenuptial agreement.

In the civil lawsuit she filed June 9 against Eric Richins’ estate, the 33-year-old murder suspect is seeking half the equity in the couple’s home, which is estimated to be worth “at least $1.9 million,” according to the filing cited by CNN.
