The mother of the boy, who fell into a gorilla enclosure, slammed the critics in a Facebook post. She said that “accidents happen”.

The gorilla was killed after the 4-year-old fell into the enclosure and the animal started dragging the boy “like a rag doll”. The incident took place on Sunday in the Cincinnati Zoo in Ohio.

The handling of the situation by zoo authority is questioned by many and it triggered an outcry. Allegedly, zoo-keepers killed 17-year-old endangered silverback gorilla with a rifle instead of just tranquilizing him.

The boy’s mother, Michelle Gregg, defended the move and said that people are too quick to judge, as reported by news.com.au.

For those of you that have seen the news or been on social media that was my son that fell in the gorilla exhibit at the zoo. God protected my child until the authorities were able to get to him,” said Gregg.

“As a society we are quick to judge how a parent could take their eyes off of their child and if anyone knows me I keep a tight watch on my kids. Accidents happen but I am thankful that the right people were in the right place today,” Gregg added in her Facebook post.

Thane Maynard, Cincinnati Zoo director, on the other hand, said that he stood by his decision to kill Harambe, the silverback gorilla. In a news conference, Maynard said that critics did not understand a silverback gorilla and also pointed that they were not present there when the incident took place, reported CNN.

Maynard said, “That child’s life was in danger. People who question that don’t understand you can’t take a risk with a silverback gorilla — this is a dangerous animal. Looking back, we’d make the same decision. The child is safe.”

Meanwhile, more than 80,000 people signed a petition to create a law which will make the visitors of a zoo responsible for the well-being of endangered animals. Another petition which blamed the child parents for the unfortunate killing and demanding an investigation has got 230,000 supporters, as per WCPO.
