(CBS) SPRING, Texas -- Gang rivalry appears to be the motive in a deadly stabbing at a suburban Houston high school early Wednesday, reports CBS affiliate KHOU, citing Harris County Sheriff's Office investigators.
Seventeen year-old Luis Alonzo Alfaro has been charged with murder in the death of Joshua Broussard, also 17. Three others were injured in the altercation. All were students at Spring High School in Spring, Texas, where the fight was reported shortly after 7 a.m. Wednesday.
Bad blood between two groups who reportedly fought earlier in the week led to the altercation, reports the station, citing officials. Alfaro allegedly told investigators after the incident that he and the victimleading to an argument and then a fight.
Alfaro reportedly said he pulled out a pocket knife and started swinging in a "back and forth" motion, an attorney said in court early Thursday.
Alfaro is held on $150,000 bail.
Parent Cynthia Bradley told the station that her daughter called her after the altercation begging her to pick her up from school.
"She said, 'Mom, the young man just fell dead on me,'" Brady said. "She said, "Momma, it was some guys, they went to fightin' and they went to stabbin... You just got to come, you just got to come.'"
Brady reportedly said she was able to get inside the school to check on her daughter before it was locked down. She said she saw the victim's body lying in a hallway.
One of the student victims was seriously injured and flown to the hospital in critical condition. He was later upgraded to "good" condition and released, the station reports.
Investigators reportedly believe two other students who were handcuffed and taken into custody were witnesses to the altercation.
