Police in Florida say no charges will be laid against a group of teens who filmed themselves mocking a disabled man as he drowned in a retention pond last week.

Jamel Dunn drowned in a pond in the city of Cocoa on July 9. Florida Today reports his body was found three days later.

"The kids were at the park that day smoking marijuana and apparently saw him walk into the water. He walked in on his own. They were watching him," said Yvonne Martinez, a spokesperson for the Cocoa Police Department, to the Florida newspaper.

"He started to struggle and scream for help and they just laughed," Martinez said. "They didn't call the police. They just laughed the whole time. he was just screaming...for someone to help him."

Police later discovered disturbing video footage, which showed a group of five teens - ages 14 to 16 - laughing as the 31-year-old man drowned.

"Get out the water, you gonna die," one teen shouted. Another yelled, "Ain't nobody fixing to help you."

When the man slips below the water the teens continue joking.

"Oh, he just died," one teen can be heard saying.

The video was released by the state attorney's office and portions of it can be found online.

The teens can be heard laughing at the man as he struggles.

Police identified the five teens involved and all have been interviewed. However, Cocoa Police Chief Mike Cataloupe says while their actions were "utterly inhumane and cruel," no criminal charges will be filed. Florida state law does not require people to give or call for help when someone is in distress.

A GoFundMe page has been created by Dunn's family to help cover funeral costs.
