CLEVELAND, OH — An unlicensed nurse has been charged with murdering a multiple sclerosis patient by feeding her a piece of bagel and letting her choke to death so she could carry on an affair with the patient's husband.

Authorities said Wanda Kanner killed Darlene Amberik in 2001 to clear the way for the relationship with John Amberik.

The victim could not feed herself or swallow solid foods.

John Amberik, 52, bought an engagement ring for Kanner, 49, four months before his wife died, police said.

Kanner was indicted Monday by a grand jury on charges of murder and involuntary manslaughter. John Amberik was charged with theft and records tampering for allegedly helping her submit false bills to an insurance company.

Kanner began working for the Amberiks in 1998, and the three moved into a home together two years later. Darlene Amberik, 49, could not feed herself or swallow solid foods.
