ST. CLOUD -- Stearns County prosecutors have charged an Albany man with murder in the death of his infant son.

32-year-old Robert Kaiser is charged with one count of second degree unintentional murder.

Records show the child was brought to the Albany Hospital after he was having difficulty breathing and was suffering seizures. The boy was airlifted to Children's Hospital where he died September 3rd.

An autopsy revealed the boy died of a traumatic brain injury, likely caused by shaking.

According to the criminal complaint, Kaiser said the boy fell while in his care, but medical experts found the testimony didn't match the child's injuries. Further investigation showed the boy had other injuries consistent with child abuse that were in the process of healing, including rib fractures.

Kaiser testified to police he was caring for the child and that the baby wasn't letting him sleep.

Kaiser's being held in the Stearns County Jail on $1,000,000 bail.
