Authorities in Florida say a group of teens ages 14 to 16 broke no laws when they were filmed on amateur cell phone video laughing while they watched a 32-year-old disabled man drown in a nearby pond.

The sickening footage was filmed just after noon on July 9 in Cocoa, Florida, when Jamel Dunn was seen pleading for help while the teens stood by and mocked him, according to Florida Today.

Dunn is heard in the video screaming for help in the final moments of his life as he struggles to keep his body afloat in the water.

Prosecutors in Brevard County released the video to the press, calling the incident a 'tragedy' while denouncing the teenagers for taking no action to help Dunn.

Authorities said there was 'no moral justification' for the behavior of the teens.

Police became aware of the video after it went viral on social media.

Dunn's body was extricated from the pond three days later.

Authorities said the teens warned Dunn, who walks with a cane, not to enter the water.

'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, Cocoa Police Department spokesperson.

'(The teens) were telling him they weren't going in after him and that 'you shouldn't have gone in there,'' the spokesperson said.

Even when it became apparent that Dunn was having trouble in the water, none of the boys called 911.

Dunn's sister launched a GoFundMe page to help pay for the funeral costs

'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.'

As Dunn fights to stay alive, the teens mercilessly taunt him.

'Get out the water, you gonna die' one teen shouted.

Another yelled at Dunn, saying, 'ain't nobody fixing to help you, you dumb (expletive).'

When Dunn loses his struggle to stay alive in the water, one of the teens is heard in the video saying: 'Oh, he just died.'

The entire group is then heard breaking out in laughter.

After the video went viral, a family friend of Dunn notified police.

When officers interviewed the teens, none of them expressed remorse.

During one interview, an officer says one of the teens just stared straight ahead and offered 'only a smirk' while the boy's mother cried.

Dunn's family was outraged.

Simone Scott, his sister, believes that the teens should be charged with a crime.

'My brother is disabled and walks with a cane…please make it make sense to me,' she said.

But prosecutors could not find any evidence of a crime.

'We are deeply saddened and shocked at both the manner in which Mr. Dunn lost his life and the actions of the witnesses to this tragedy,' the State Attorney's Office said in a statement.

'While the incident depicted on the recording does not give rise to sufficient evidence to support criminal prosecution under Florida statutes, we can find no moral justification for either the behavior of persons heard on the recording or the deliberate decision not to render aid to Mr. Dunn.'

Investigators said Dunn had gotten into an argument with his fiancée at the pond about 15 minutes before the drowning.

The fiancée left the scene and Dunn stayed, according to police.

Scott has set up a GoFundMe page asking donors to help defray the cost of the funeral.
