The Latest on the shooting of a Cincinnati Zoo gorilla after a small child got into its enclosure (all times local):

An Ohio prosecutor is reviewing the investigation into the actions of the family of a 3-year-old boy who got into a Cincinnati Zoo gorilla enclosure, leading to the fatal shooting of a gorilla.

A spokesman for Hamilton County Prosecutor Joe Deters (DEE'-turs) says Cincinnati police have concluded their probe. He says the earliest Deters will make a decision on whether charges should be pursued is Friday. Legal experts say a prosecution in the case seems unlikely.

A Cincinnati police report identifies the boy's mother as 32-year-old Michelle Gregg, who works at preschool near Cincinnati. The Cincinnati Enquirer first obtained the report.

The family says the boy is doing well at home after being treated at a hospital.

A spokeswoman says the family requests privacy and has no comment on the investigation.

No decision has been made yet on whether charges will be brought against the parents of a 3-year-old boy who fell into a gorilla enclosure at the Cincinnati Zoo, causing an animal response team to shoot and kill the primate, authorities said.

Meanwhile, 911 tapes released Wednesday by Cincinnati police reveal the confusion and panic in the moments when the boy plunged into the zoo's gorilla exhibit.

"He's dragging my son! I can't watch this!" a woman, who isn't identified, says in the 911 call on Saturday.

As she pleads for help, she shouts at her son repeatedly: "Be calm!"

The zoo's dangerous animal response team shot and killed the gorilla within 10 minutes to protect the boy after he dropped some 15 feet into a moat.
