A Cheyenne man arraigned Friday in Laramie County District Court denied any wrongdoing in the death of his then-girlfriend’s baby.

Tyler Miller, 26, pleaded not guilty to one count of aggravated child abuse in the child’s death.

Prosecutors charged Miller in March. He could face up to 25 years in prison if convicted.

Public defender Brandon Booth argued the court should reduce Miller’s bond amount from $10,000 to $1,000 because the state does not have evidence against him. Booth also questioned why Miller was only one charged in the case.

Booth claimed some six or seven other people were taking care of the baby the day before Miller cared for the child.

Laramie County District Attorney Jeremiah Sandburg later responded, "The child is dead." He argued Miller’s bond should remain unchanged and a jury should decide Miller’s fate, regardless of whether the defense believes the evidence is weak.

Laramie County First District Court Judge Thomas Campbell left the bond set at $10,000.

In April, the baby's mother admitted the 4-month-old baby to the Cheyenne Regional Medical Center, according to court documents. The baby was then flown to Children’s Hospital Colorado.

The baby was said to have a subdural hematoma and died a week later.
