SPRING -

Authorities said the motive of Wednesday's stabbing at Spring High School appears to be gang rivalry.

The teen accused of killing one student and injuring three others in the stabbing appeared in court early Thursday morning.

Seventeen-year-old Luis Alonzo Alfaro is charged with one felony count of murder. He appeared at 2 a.m. in magistrate court.

According to court documents, Alfaro entered the cafeteria at Spring High School Wednesday morning. He bumped a male student with his shoulder, the two of them exchanged words and the student was then shoved by Alfaro. 

Court documents state a black male punched Alfaro, which started a fist fight between them. Alfaro then pulled out a pocket knife and started swinging it.

Alfaro fled the campus as the crowd began to disperse, according to court records. The victim, later identified as 17-year-old Joshua Broussard, suffered multiple wounds to his abdomen consistent with a sharp-edged instrument and collapsed and died in a hallway near the cafeteria.

Court records show Alfaro was later found by police who had responded to the school for an initial report of a stabbing.

Alfaro is being held in the Harris County Jail on $150,000 bond.

Alfaro is due in district court on Friday where a court-appointed attorney is expected to be assigned.

The stabbing happened around 7:10 a.m. Wednesday at Spring High School.

The sheriff's office confirmed that three people were injured and one person was killed during the incident that started with a physical confrontation involving a "cutting instrument."

One of the three students, a 16-year-old boy, was transported via LifeFlight to Memorial Hermann Texas Trauma Institute. He's listed in good condition.

Two other patients were transported via ambulance to Houston Northwest Medical Center with minor injuries. Of those two victims, one was transported to Memorial Hermann Texas Trauma Institute Wednesday afternoon in good condition.

Spring ISD cancelled classes for Spring High students on Thursday and Friday. Classes will resume on Monday.

The district says crisis counselors will be available to assist students and extra security will be on campus.

Spring ISD has set up an informational hotline for parents to call with questions for the school. The number is 281-891-6575 and calls can be made Thursday and Friday between 10 a.m. and 2 p.m.

Anyone with information about the stabbing incident is asked to call Crime Stoppers at 713-222-TIPS.

The Harris County Sheriff's Office does not expect any other charges in this case.
