The victim, identified by family members as Michael Brewer, suffered burns over 75 percent of his body, especially on his torso and arms, sheriff’s spokesman Jim Leljedal said.

15-year-olds Matthew Bent, Denver Jarvis, Steven Shelton and Jesus Mendez and 13-year-old Jeremy Jarvis were charged with aggravated battery.

Mendez was also charged with attempted second-degree murder because authorities say he flicked the lighter.

Witnesses say the victim was sitting by a swimming pool at about 3:15 p.m. when the three teens allegedly approached him and confronted him “over money they said he owed them.”

Then, he said, the victim was held down while the alcohol was poured on him, and someone lit the blaze.

Brewer, a seventh-grader, jumped into the pool to put out the fire, the judge said.

Family members said most of his hair, including his eyelashes, had been burned off.

The Jarvis brothers and Bent were each ordered held in a juvenile detention center for 21 days, and will not be allowed to speak to each other, Williams said.

They were also ordered not to contact Brewer.

Lawyers for the younger Jarvis brother and for Bent said their clients were “minimally involved” in the attack.

Attorney Stephen Melnick said Jeremy Jarvis was “just there. He was not accused of actually doing it.”

Attorney Gordon Weekes, representing Bent, said his client “understands the gravity of the charges.”

Doctors scraped Brewer’s burns Monday night at Jackson Memorial Hospital while he was under anesthesia, according to brother-in-law Danny Martinez. Brewer woke up this morning and was given more anesthesia so he would go back to sleep.

“He’s doing pretty good,” Martinez said this morning. “He’s still serious though.”

During the Monday attack, Brewer screamed for help, said his sister, Malissa Durkee, 22.

Her brother then ripped off his shirt and jumped in the pool, she said.

Detectives suspect the attack at the Lime Tree Apartments on the 400 block of Southeast 13th Court was tied to an incident the day before, when Brewer stopped someone from stealing his father’s bicycle.

Martinez said Brewer, a student at Deerfield Beach Middle School, had refused to go to school Monday because of Sunday’s incident. Sheriff’s officials said he had gone to the apartment complex to visit a friend.

After the attack, Brewer was taken by helicopter to Broward General Medical Center, then transferred to Jackson Memorial Hospital’s burn unit in Miami. He’s expected to stay at the hospital for up to five months, Martinez said.

The five were not charged as adults but Leljedal said the sheriff’s office typically releases the names of anyone charged with a felony, regardless of age.
