ATCHISON -A Kansas mother is facing multiple charges in connection with life-threatening injuries sustained by her infant son.

Authorities say Heidi Pace, 22, was charged with Abuse of a Child and Aggravated Battery.

Atchison County Sheriff Jack Laurie said they began investigating April 7 after being alerted by Child Services at Children’s Mercy Hospital.

“They advised us that they had received a 3-month-old male child down there that had possibly been abused in some manner,” Laurie said. “The baby had originally been taken to Horton Hospital and was then flown for additional treatment at a larger hospital.

Laurie said the infant has suffered some severe brain damage and a ruptured spleen. He said the child is in serious condition.

Pace was arrested Tuesday morning in Muschotah, Kan.

Laurie said Pace is being held in Atchison County Jail on $100,000 bond cash or surety.
