Man accused of spiking wife's cereal with heroin convicted of murder after breast milk sample helps prove case

A Michigan man accused of spiking his wife's cereal with heroin was convicted of murder and other crimes Wednesday.

The medical examiner had classified Christina Harris' death in 2014 as an accidental overdose. But investigators subsequently alleged that it was a murder scheme hatched by Jason Harris at their Davison home in Genesee County.

Family members insisted that Christina didn't use drugs. Indeed, a sample of frozen breast milk showed no evidence of it.  It marked the first time Michigan officials had used breast milk as evidence in a criminal case, WDIV-TV reported.
