Three teenagers accused of setting a 15-year-old south Florida boy on fire have pleaded not guilty to attempted second-degree murder.

Denver Jarvis and Matthew Bent, both 15, and 16-year-old Jesus Mendez are charged as adults. The Broward State Attorney's Office said the teens pleaded not guilty on Thursday.

Authorities say Jarvis poured rubbing alcohol on Michael Brewer on Oct. 12 in Deerfield Beach. Mendez is accused of lighting Brewer on fire, and Bent is accused of directing the attack.

Brewer sustained burns over 65 percent of his body and is still in critical condition at Jackson Memorial Hospital.

The teens are set to appear again in Broward County court on Jan. 15.
