WEST JORDAN, Utah (KSTU) -- A West Jordan mother will serve up to 15 years in prison after her 13-day-old baby Archer was beaten to death.
A judge sentenced Maria Sullivan Monday to serve 1 to 15 years in prison for two child abuse charges, served concurrently.
Dylan Kitzmiller, Sullivan's boyfriend at the time, will be sentenced in July for the two child abuse charges as well.
Court documents say Kitzmiller broke baby Archer's bones, injured his brain and spinal cord, and left cuts and bruises all over.
Sullivan took a plea deal to drop the charge of murder to two counts of child abuse. A jury found Kitzmiller guilty, also on two counts of child abuse.
But Archer's biological father Jaymie Waters feels let down.
"I had trusted our government agencies and that they would do their job," Waters told the judge at the sentencing. "I feel like no one did, and no one cared."
Waters told the judge he tried to intervene after baby Archer was born with opiates in his system, but he had been cut off from having contact with Sullivan.
He said the Department of Child and Family Services wouldn't step in.
