Teen, 15, accused of stabbing at Miami Northwestern Senior High charged as adult

A teen accused of stabbing a student at Miami Northwestern Senior High School after a fight is being charged as an adult, records show.

Carlos Martinez, 15, is facing several charges, including aggravated battery with a deadly weapon, possession of a weapon on school property, and educational instruction interference.

NBC6 is naming Martinez because he is being charged as an adult.

According to the Miami-Dade Sheriff’s Office, on Aug. 31, deputies arrived at the high school after receiving reports of a stabbing.

An arrest report said Martinez was taken to the hospital for self-inflicted injuries he received during the incident, and a victim was taken to the hospital as well.

Detectives then spoke with the victim, who told them he didn’t know who Martinez was and saw him being jumped by two other children and was watching the fight, the report said.

Cellphone video shows two people appearing to team up as they attack a student in a hallway before that student appears to go after them.

The victim, the report said, told detectives that when everyone started running away, he felt a push in his back and thought it was one of the other students who were running that pushed, but another student told him he was bleeding and noticed that something was dripping from his back. He said he never interacted with Martinez.

Back at the school, detectives were able to recover a knife that was described as having a 5-inch blade and was overall 10 inches with the blade and the handle, the report said.

Surveillance video at the school, the report said, showed Martinez being involved in a physical altercation with two other students, and he was seen reaching into his pants and pulling out a blade-shaped object. Martinez then was seen sprinting down the hallway to retaliate, and was last seen going down the hallway to get his things, put the bladed object back in his pocket, before trying to leave.

After Martinez left the hallway, the school’s principal saw him fleeing into the parking lot and asked him why he was bleeding, which Martinez admitted to having a knife, the report said. The principal then took the knife.

During the incident, the school was placed on lockdown.

The victim, the report said, suffered a puncture wound on the right side of his back, which needed stitches, while Martinez had several self-inflicted lacerations to his fingers.

After he was treated, Martinez was arrested.

During his court appearance on Saturday, Martinez’s attorney claimed that he had been bullied at the school and he was allegedly drowned by the two students.

“Mr. Martinez was being severely bullied at the school,” the attorney said. “He was drowned by two individuals at the school. It was a violent encounter.”

His attorney said Martinez acted in self-defense following that incident.

“And we’ve presented a ton of mitigation to the state as it relates to this being completely out of character and out with direct result of the constant bullying that he was undergoing,” his attorney said. “We have letters from the principals, from his teachers that support this assertion.”

In court, Martinez’s attorney said the state will be bringing charges against the two students who allegedly jumped him.

“He’s also cooperating with the state because they are bringing charges against the two juveniles that jumped him,” Martinez’s attorney said.

Ultimately, the judge set Martinez’s bond at $6,150 and ordered that he be placed on house arrest.
