Michigan man convicted of murdering his wife by spiking her cereal with heroin

A Michigan man faces life in prison after he murdered his wife seven years ago by spiking her cereal with heroin.

A jury convicted Jason Harris, 47, of Davison on Nov. 17 of first-degree premeditated murder, and delivery of a controlled substance causing death.

In 2014, the Genesee County Medical Examiner ruled the death of Christina Ann Thompson Harris an accidental overdose.

Family, however, countered the victim had no history of drug use. “In conversations with her, there were things that were upsetting her [in the marriage],” the victim's mother, Kathy Mays, told WDIV-TV two years ago.

In August 2019, five years after Harris’ death, her manner of death was changed to homicide and authorities took her husband into custody.

Evidence against the defendant included a sample of frozen breast milk investigators tested that showed no signs of heroin, proving the mother of two children, now ages 12 and 7, had none of the drug in her system.

Prosecutors also built their case against Harris’ husband by revealing he had affairs during their marriage, detailing a failed alleged murder-for-hire plot, and pointing out a $120,000 insurance payout.

Next month, Jason Harris is expected to be given a mandatory life sentence without the possibility of parole.

“This was a very tragic case and my heart goes out to the family and friends,” prosecutor David Leyton said.
