Conviction Upheld After Cheating Husband Poisons Wife’s Cereal with Deadly Heroin Dose

The Flint appeals court in Michigan has upheld the conviction against a man who poisoned his wife’s cereal in 2014, killing her.

As CrimeOnline previously reported, Jason Harris was found guilty of fatally poisoning his wife, Christina Ann Thompson Harris, 36, with heroin. Despite Harris’ appeal citing ineffective assistance of counsel, the court rejected his argument, solidifying his 2021 conviction on all counts.

On Monday, the Genesee County Prosecutor’s Office confirmed that the conviction was upheld.

“The evidence in this case was overwhelming and, I am pleased with the decision reached by the Court of Appeals,” Prosecutor David Leyton said, according to WNEM. “Justice for Christina Harris and her family has once again been achieved in a court of law.”

Christina Harris was found dead in September 2014 of what investigators called a drug overdose.

A neighbor told police that Jason Harris said he had given his wife a bowl of cereal the night before she was found dead, and that she dropped the bowl and passed out. Jason Harris’s brother and sister told investigators in October 2014 that Harris had been unfaithful to his wife and had talked about “getting rid” of her.

After the Michigan State Police took over the investigation in 2016, detectives found items on the husband’s cell phones that supported the claims he had been cheating on his wife.

Detectives also found nearly 6,000 text messages between Harris and a woman from Rhode Island, in addition to communications and photos sent to multiple other women. Nine days after Christina’s death, he flew to visit the woman in Rhode Island.

Within two weeks of Christina’s death, a woman and her daughter moved in with the convicted killer. Harris also collected $120,000 in life insurance benefits.

During his 2021 sentencing hearing, Harris didn’t apologize and asserted his innocence. Christina’s mother, Kathy Mays, said the family now feels a sense of relief that Harris will be in prison for life. He is not eligible for parole.
