Former McHenry resident Linda La Roche found guilty of murdering nanny Peggy Lynn Johnson

RACINE COUNTY, Wisconsin - Linda La Roche, the McHenry woman accused of killing housekeeper/nanny Peggy Lynn Johnson and dumping her body in a southern Wisconsin cornfield in 1999, has been found guilty of criminal charges. 

A jury in Racine County on Wednesday found 66-year-old La Roche guilty of first-degree intentional homicide and hiding a corpse. 

For nearly two decades the victim was known only as Jane Doe. Advances in DNA technology eventually led to her identification as 23-year-old Peggy Lynn Johnson. 

She lived with La Roche and her family at their home in McHenry, Illinois where she worked as a nanny and housekeeper. 

La Roche was accused of physically abusing Johnson for years, which led to her death.
