The mother of a Utah woman charged in her husbands overdose death after penning a childrens book about grief also lost a romantic partner due to a suspicious drug overdose, a newly unsealed search warrant affidavit shows.

Kouri Richins mother, Lisa Darden, was subjected to a phone search last year after a detective investigating Eric Richins 2022 death discovered the similar overdose in 2006, according to the affidavit filed in Summit County in May of last year.

Based on Lisa Dardens proximity to her partners suspicious overdose death, and her relationship with Kouri, it is possible she was involved in planning and orchestrating Erics death, Summit County Sheriff Detective Jeff ODriscoll stated with the request to search Dardens phone records.
