Corey Johnson was identified in court at the suspect in a deadly stabbing Monday in BallenIsles.
The 17-year-old is charged with one count of murder and two counts of attempted murder after a woman and two juvenile males were stabbed. One of the juveniles died from his injuries.
"Corey Johnson has confessed his actions to our investigators stating that he stabbed the victims because of his religious beliefs," said interim Palm Beach Gardens Police Chief Clint Shannon.
"Our understanding is he had converted to Islam and had been watching violent videos online," Shannon said.
Palm Beach Gardens Major Paul Rogers said their suspect was a guest at the house where the stabbings took place.
Johnson was a student at Dwyer High School and recently withdrawn, according to police.
The FBI is now involved in the case.
This is a developing story and will be updated.
