Three Delaware teenagers involved in videotaped assaults of a mentally disabled man have been sentenced to probation and house arrest , followed by placement in a secure juvenile facility . The teens were sentenced Monday after each pleaded guilty to a single felony count of crime against a vulnerable adult . The boys , two 15-year-olds and a 14-year-old , were sentenced to probation and house arrest for the rest of the school year , followed by summer placement at a juvenile facility . Videos posted online showed the 27-year-old victim being body-slammed to the ground , stomped on and kicked , and repeatedly punched in the head . Scroll down for video . Attack : The victim ( in gray ) can be seen trying to stop the youths from attacking him . Violent : One of the boys picks the man up before throwing him to the ground . Others can be heard laughing . Hurt : The man , who can be heard groaning , was reportedly treated at the hospital afterwards for injuries . The defendants were charged with offensive touching , assault of a vulnerable adult , and conspiracy . Prosecutors later added hate-crime charges , which were dropped along with other charges following the guilty pleas . A video that was posted to YouTube shows a group of teenagers pursuing the victim as he shouts : 'Leave me alone ! ' One boy swings at the man , repeatedly punching him , before picking him up and throwing him to the ground on at least two occasions . The boys then crowd around the man - while one teenager who is filming the attack on his cellphone nears the man to get a closer shot as he writhes on the floor . A separate video reveals them attacking the man in a wooded area , Fox29 reported . In that attack , the victim can be heard crying , while a female voice says : 'You guys are so mean to him . ' In September , the victim 's mother Yana told WPVI that while initially seeing the video she felt 'Rage , anger - because of the situation , with him being mentally disabled , he does n't do anything to anyone but be kind . ' Yana told the television station her son Karon has Williams Syndrome . Those with Williams Syndrome often have an intellectual disability , heart defects , a slight stature and distinctive facial features , including a flat nasal bridge . Sufferers are often extremely friendly . 'He 's not doing too good , ' his godmother Debra Jackson told CBS3 in September . 'One , he 's ashamed about it happening , he ’ s embarrassed . ' She added that her godson thought the teenagers were his friends . That same month , one teenager who appeared in footage told CBS 3 that he assisted in reporting what happened . He said the assaults were filmed in Newark . He told the television station at the time 'The right thing to do was call the cops . If you beat up a mentally disabled person , you should be locked away for good . ' Cruel : As the group surround him , one of the teenagers ( with the backpack ) is more concerned about getting a close-up snap of the victim than helping him . Concern : The victim 's godmother and sister ( seen in September ) said that he is ashamed and thought the teens were his friends . See video below .
