SEABROOK — Three teenagers have been indicted for an alleged attack on an autistic 18-year-old who was beaten, burned with cigarettes and spit on at a Seabrook home while several people recorded the incident and laughed, police said.

The teenage victim claims videos of the Oct. 17 incident were posted on Snapchat.

Seabrook police later reviewed the video clips and described the victim as “defenseless” as he pleaded with one of his accused attackers to stop.

A Rockingham County grand jury handed up indictments this month against Israel Junior Rivera, 18, of Seabrook; Paul Dustin, 18, also of Seabrook; and Brandon Lemieux, 19, whose address is listed as homeless.

Rivera is charged with criminal restraint, criminal mischief, and tampering with witnesses and informants. He is accused of confining the victim for two hours by repeatedly punching and/or kicking him while others also punched him and burned his hair. He also allegedly smashed a windshield with a cinder block and then tried to force the beating victim to falsely claim responsibility for the windshield damage.

Lemieux and Dustin face one count each of criminal restraint alleging that they also confined the victim and punched him while others punched and burned his hair.

An indictment is not an indication of guilt; rather, it means a grand jury found enough evidence to bring the case to trial.

According to a police affidavit by Seabrook patrolman Zachary P. Bunszell, the victim told police that he was assaulted by a group of people on Oct. 17 at a residence on South Main Street and that his iPhone was stolen.

The victim, who was described by police as having a “low level” autistic disorder, stated that he went to a friend’s house to get some belongings and that when he arrived Dustin, Lemieux, and three other teenagers ages 15, 16, and 17, were at the residence.

He told police that he was encouraged to hang out and “smoke a few blunts,” the affidavit said.

The teen stated that Dustin said he was “leaving to go buy blunt wraps” and returned moments later with Rivera.

“I was very hesitant to stay. I stayed though because I was being an extreme idiot,” the teen told police.

When Dustin returned, the teen said Rivera punched him in the face three times when he went to greet him.

“After that I was completely humiliated, most of the people at (the house) were spitting on me, physically abusing me, flicking ash in my hair, kicking me and making me admit crimes I did not commit,” he told police.

The teen described Rivera, who is known as “Izzy,” as the “main abuser” and alleges that Rivera wanted him to admit that he smashed up a friend’s vehicle, which he claims he didn’t do.

Police noted that the teen was injured and appeared to have bruises and swelling and wrote that “many people at the residence had been flicking cigarette butts at him and spitting on him as well.”

The three teens are scheduled to be arraigned on the charges in Rockingham County Superior Court on April 4.
