Five years after his wife’s sudden death, a Michigan man has been charged with killing her — by spiking a bowl of cereal with heroin.

According to MLive, Christina Ann-Thompson Harris, 36, of Davison, was found dead in September 2014 of what authorities initially believed was a drug overdose –– but Harris’s friends and family never knew the mother or two to be a drug user.

A neighbor reportedly told police that Christina’s husband 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. Also, Jason Harris’s brother and sister told investigators in October of 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, according to the MLive report. A woman moved into the home only two months after Christina died.

Further, the investigation reportedly found that Harris had asked two people to kill his wife, offering both of them money.

Genesee County Prosecutor David Leyton told the news outlet that Christina had expressed some concern that her husband might hurt her, and told a friend that if anything had happened to her, to look at Jason.

It is unclear what evidence prompted police to arrest Jason Harris five years after his wife’s death, as much of the witness testimony appears to have been obtained early in the investigation.

“We believe Jason Harris murdered his wife,” Leyton told MLive. “We believe he put heroin into her cereal and milk the night that she died after getting it from someone, thinking it would be tasteless and odorless much like he had asked his coworkers multiple times.”

Harris has been charged with first-degree murder, solicitation of murder and delivery of a controlled substance causing death, MLive reports.

According to the New York Post, Harris is being held without bond and his lawyer said he will plead not guilty.
