(CBS/AP) In 1957, a 7-month-old baby girl with brain injuries was pronounced dead at a Wisconsin hospital. This week - 54 years later - her mother, Ruby Klokow, was charged with second-degree murder in the death of her baby daughter, Jeaneen.
Klokow, now 74, was arrested Monday and charged Tuesday, more than two years after her adult son came forward with information in the case. The baby's death had been listed as accidental.
Prosecutors say Ruby Klokow has confessed to causing the fatal injuries to the infant, when she was a 20-year-old mother.
Klokow appeared Tuesday in Sheboygan County Circuit Court where a $10,000 cash bond was ordered. Prosecutors say Klokow threw the baby onto a couch when she became angry with the child. The baby suffered brain injuries when she bounced onto the floor.
The criminal complaint against Ruby Klokow alleges she had a history of abusing her children, according the CBS affiliate WFRV.
The Sheboygan Press reports that an investigation was re-opened in 2008 when Klokow's son, James, told police he believed his mother was responsible for the death. James Klokow says his mother had long blamed him. The complaint says another child, Scott Klokow, was found dead in his crib in 1964, but prosecutors say there's no evidence to prove foul play.
The bodies of both children were exhumed in July.
WLUK-TV says Ruby Kloklow is charged with second-degree murder under the Wisconsin state law in place in 1957.
