A Michigan prosecutor on Friday provided horrific details of the abuse heaped upon a 6-year-old boy who was found dead in his home last week.

Giovanni “Chulo” Jennings’ mother, Elaina Jennings, called 911 on July 30 and reported her son was unconscious, Oakland County Prosecutor Karen McDonald said. When officers arrived, the boy was unresponsive and had multiple injuries, WJBK reported.

He was taken to Ascension Macomb-Oakland Hospital and then to Children’s Hospital, where he died from his injuries. An autopsy determined that he died from blunt force trauma and perforated abdomen, and he died “after a lengthy period of confinement and abuse,” McDonald said.

Elaina Jennings and her boyfriend, Daniel Giacchina, were charged with multiple counts last week but did not face charges in the child’s death until this week.

“We have spent over 100 hours reviewing extremely disturbing videos and photos, as well as text messages and Facebook chats describing the horrific things that happened to this 6-year-old boy,” McDonald said. “What we found can only be described as horrific.”

Chulo had bruising and lacerations on every part of his body, McDonald said, including inside his mouth. His abdomen was bloated, and he had an apparent wound from a BB. McDonald said the boy’s 4-year-old brother said during an interview at a child advocacy center that Giacchina shot both boys with a BB gun.

Chulo was confined to a pen in his mother and boyfriend’s bedroom, where he slept on an 11-inch by 36-inch wooden board. The pen included restraints to keep him inside and curtains to keep him from seeing out. The couple kept tabs on him with a security camera and punished him if he misbehaved. Misbehavior including trying to take a drink, trying to urinate, or trying to get out of his prison.

At one point, McDonald said, the couple stapled him face first to the floor by his clothes because he dared to look out a window.

McDonald said the evidence investigators uncovered showed that Jennings knew about the abuse and occasionally encouraged it but never once got medical help for the child’s injuries.

Messages between the couple included a photo of Giacchina sent to Jennings of Chulo stapled to the floor with his head wedged into a corner. The message said he’d solved the problem of keeping the boy’s head in the corner. Both of them laughed about it.

“This is one of the worst cases we’ve seen,” McDonald said of the abuse.

There was another photo, the prosecutor said, of children handling an actual handgun and a BB gun. Another photo showed two children pointing a gun at a third child.

On the day of the boy’s death, Jennings told police the child had been with his biological father, prompting that man’s arrest. When police questioned him and realized he was not involved and the child had not been with him, he was released.

Instead, McDonald said, Giacchina was home with all the children that day while Jennings was a work, a normal state of affairs.

The younger brother, who was interviewed at the child advocay center Care House, told investigators that “Chulo died all day and Danny was there.” Chulo’s younger brother said during the interview at Care House.

McDonald said that Jennings was well aware of the abuse and occasionally encouraged it but never once took the boy for medical treatment for his injuries, including an incident a few days before the child’s death when Jennings admitted that her boyfriend punched the child in the stomach several times, causing him to throw up. It wasn’t the first time Giacchina had beaten the boy.

“It was clear from the evidence that we saw that there was a period of abuse that led to Chulo’s death,” McDonald said.

Jennings and Giacchino have now been charged with murder and first degree child abuse in the boy’s death. They are being held without bond.

Last week, Giacchina was charged with firearm possession by a prohibited person, ammunition possession by a felon, felony firearm, and lying to a peace officer. Jennings was charged with lying to a peace officer.
