One person is dead and three others injured after a stabbing Wednesday morning at Spring High School.
The dad and aunt of 17-year-old Joshua Broussard confirmed to Houston's KPRC that the sophomore was killed in the stabbing.
"I went in, but I didn't want to go all the way to see him laying on the ground. That would have been too drastic," said Jason Broussard, Joshua's father.
The Harris Co. Sheriff's Office said they are questioning a 17-year-old male who is now considered the sole suspect in the case.
It happened around 7:10 a.m. at Spring High off I-45. Authorities said the school's nurse called police saying multiple people had been stabbed.
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."
Sources said the trouble may have started on Tuesday, when Broussard elbowed another student's girlfriend.
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.
Deputies earlier took four persons of interest into custody to question them. Two of them -- a 16-year-old and a 17-year-old -- are now considered witnesses to a crime, according to investigators.
All of the victims and three of the persons of interests are students in Spring ISD, according to the Sheriff Garcia.
Detectives also took an adult relative of one of the suspects into custody after he refused to cooperate with investigators when they went to his house.
Joshua Broussard's grandfather, Robert Johnson, said all he wants is justice.
"I think they need to be caught and prosecuted," said Johnson.
Authorities have not recovered the weapons used during the incident.
Anyone with information about those involved with the stabbing, what weapons were used or where the weapons are should call the Harris County Sheriff's Office at 713-967-5810 or the Crime Stopper tip line at 713-222-TIPS.
Sheriff Garcia said investigators were looking into suggestions that the stabbings were related to gang activity. However, deputies had not been called to the school about gang violence before Wednesday.
Broussard's family said the teen had nothing to do with gang relations.
"He wasn't a bad kid, he wasn't with no gangs or none of that. He was straight books and school," said Jason Broussard.
Jason Broussard also said his son was a true cowboy.
"He was in the rodeo, teen roping. (He) liked horses, cattle, anything to do with farming," said Jason Broussard.
Jason Broussard believes his son was just in the wrong place at the wrong time.
According to investigators, there was an apparent fight on Tuesday that led to Wednesday morning's tragedy. Just before the bell rang, someone allegedly bumped one of the victims as he walked through the cafeteria. A fistfight erupted and quickly turned deadly.
Investigators believe only one of the four suspects was armed with a knife and in just a few seconds he managed to stab all four victims.
The school was placed under lock down shortly after the stabbing was reported.
