TUCSON, Ariz — An Arizona man accused of killing his girlfriend’s 4-month-old baby pleaded guilty Monday to charges of second-degree murder and child abuse, prosecutors said.
Investigators said they found the infant unresponsive while Liggens was babysitting the child, the news outlets reported. Emergency crews rushed the baby to a nearby hospital, where doctors noticed signs of head trauma. The infant later died, officials said.
Prosecutors also alleged that Liggens abused the baby’s 3-year-old sibling, according to the news outlets.
Liggens’ sentencing is set for April 6, officials said.
