Deters added the mother’s actions were “not even close” to meriting a reckless endangerment charge.
Witnesses told investigators that the mother was attentive to her children, turning her back on the 3-year-old for only a few seconds.
“I don’t know about you all, but I might have been dead that day. Because I would have gone in there,” Deters said.
Deters added that the Cincinnati Zoo won’t be charged. “I don’t know what the charge would be,” he said. “I can’t imagine any charges against them.”
A number of people on social media and elsewhere petitioned to get the mother charged with a crime---saying the gorilla didn’t deserve to die.
The zoo responded by erecting a higher, more secure barrier around the gorilla pit. The zoo plans on opening up the gorilla enclosure for the first time since the incident on Tuesday.
“Our exhibit goes above and beyond standard safety requirements, but in light of what happened, we have modified the outer public barrier to make entry even more difficult,” said Thane Maynard, head of the Cincinnati Zoo, in a statement.
The U.S. Department of Agriculture and the Association of Zoos and Aquariums have said they will investigate the incident.
“In the case of this incident, which involved a child and a critically endangered animal, our collective goal is to take steps to assure it doesn’t happen again,” Kris Vehrs, head of the zoo association, said in a statement.
Police also released the 911 call recording after the child fell.
“He’s dragging my son! I can’t watch this!” a woman says in the 911 call, pleading for help. She shouts at her son repeatedly: “Be calm!”
A record of police calls shows nine minutes passed between the first emergency call about the boy falling into the enclosure and when the child was safe.
The police report states that witnesses said the gorilla initially appeared to be protecting the child, but after onlookers started screaming, it became “agitated and scared” and began dragging the child.
The boy’s family has expressed gratitude to the zoo for protecting his life.
“Some have offered money to the family, which we do not want and will not accept,” the family said in the statement. “If anyone wishes to make a gift, we recommend a donation to the Cincinnati Zoo in Harambe’s name.”
