Court Papers: How Dr. St. Claire Allegedy ‘Poisoned’ His Wife

In divorce court papers filed Oct. 22, 2024, Cassandra Fameux’s lawyer Timothy Young detailed how Dr. Paul Gregory St. Claire, the former anesthesiologist at the University of Michigan Health Sparrow, allegedly poisoned his Haitian immigrant wife with antipsychotic drugs including Invega Sustenna and made her sign a Judgement of Separate Maintenance (JOSM) while she was allegedly under the influence of the drugs; the JOSM transferred 100% of marital assets–millions of dollars and two homes to Dr. St. Claire. It also gave him advantage in custody of their then minor three children by appointing his alleged co-conspirator Dr. Dominic Barberio as the psychiatrist who would determine Ms. Fameux’s mental fitness to co-parent.

Divorce court Judge Carol Koenig, in Ingham County, denied the motion to set-aside the JOSM. Black Star News reported in an article in November, 2025, that the JOSM was nevertheless apparently void since the court had never appointed a Guardian Ad Litem (GAL) for Ms. Fameux before she signed the agreement.

Black Star News reported that Judge Koenig schemed with St. Claire and his then divorce lawyer Jessica Larson and fabricated the existence of a GAL. Judge Koenig then upheld the JOSM in her final divorce court rulings in September and November 2025.

Black Star News reported this alleged fraud involving Judge Koenig to: the Michigan Commission on Judicial Tenure; Ingham County Chief Circuit and Probate Judge Shauna Dunnings; Gov. Megan Whitmer; State Attorney General Dana Nessel; Ingham County Prosecutor John Dewane; the US Attorney General; and, the FBI.
