Police arrested a Boise couple Tuesday on child abuse charges in connection with an incident late last year where their 4-month-old son was treated for broken bones — including his ribs and both legs.

Jacob D. Mast, 21, is charged with aggravated battery, and Nicole R. Henneck, 18, is charged with felony injury to child.

Boise police began investigating Nov. 22 after getting a call from hospital officials, who were treating the child for broken bones and saw signs of abuse, according to reports. Police arrived and declared the infant to be in imminent danger. The child was then put in the custody of the Idaho Department of Health and Welfare.

Ada County prosecutors issued arrest warrants for the couple Tuesday and Boise police arrested them later in the afternoon, according to jail records.

Officials released little other information about the case Wednesday but the charges indicate police suspect Mast struck the infant because he is charged with aggravated battery, a crime punishable by up to 15 years in prison.

Prosecutors say Mast beat the child and and Henneck did not call police or seek medical attention for the boy when the abuse occurred between October and November, according to court records obtained by the Idaho Statesman Wednesday.

Prosecutors also say witnesses told police they saw Mast put both of his feet on the back of his son while the baby was laying face-first on the floor. Those same people also told investigator they saw Mast tie a "binky" in his son's mouth so he couldn't cry and heard him saying he didn't like the boy.

Prosecutors also say the boy was born prematurely in July and required extra medical care but his parents stopped giving him extra oxygen, according to court testimony.

Henneck is charged with felony injury to child, a crime punishable by up to 10 years in prison. Police can charge that crime if there is evidence that someone allows a child to be in “circumstances or conditions likely to produce great bodily harm or death, (or) willfully causes or permits any child to suffer” or “willfully causes or permits such child to be placed in such situation that its person or health is endangered.”

Defense attorney John DeFranco, who is representing Henneck, told a judge Wednesday they would aggressively fight the charge in the case and said "there is nothing to suggest she is a dangerous person."

DeFranco asked for Henneck to be released from jail but 4th District Magistrate Judge John Hawley set Henneck's bond at $100,000.

As of 2:30 p.m. Wednesday, Mast had not yet made his initial court appearance. He is being held in the Ada County Jail on a $500,000 bond.

Preliminary hearings in the case will be set for later this month.
