That’s according to Dr. Michael Graham, chief medical examiner, for the city. Graham, whose office routinely investigates the sudden, unexpected deaths of young people, said Walker died of the “sudden onset of a lethal cardiac rhythm disturbance that was caused by underlying heart muscle disease,” formally classified as “nonischemic cardiomyopathy.”
No illegal drugs were found in her system and alcohol “had nothing to do with her death,” Graham said.
The finding confirmed an earlier St. Louis Police Department inquiry that uncovered no “suspicious” activity in the death of the 37-year-old who left state government in 2019 to work for St. Louis County Executive Sam Page.
Graham said there was no indication that Walker was being treated for the underlying heart disease that claimed her life, though she did have normal doses of other prescribed medications in her system.
“She was not being treated for any heart disease,” said Graham. “She was unaware that she specifically had this going on.”
