PHOENIX -- A man accused of killing his wife at their Scottsdale home has pleaded guilty to second-degree murder.
Michael Cohn, 62, entered his plea Monday. Sentencing is set for Jan. 6.
Cohn originally pleaded not guilty to a first-degree murder charge in April.
Police said Cohn called 911 on March 27 and told the operator that he had strangled his wife.
Responding officers found Linda Cohn's body in a bathroom of their home near Bell Road and Thompson Peak Parkway.
Linda Cohn, 60, was a psychologist specializing in substance-abuse counseling.
