One student is dead and three others were injured in a stabbing at Spring High School near Houston Wednesday morning, according to the Harris County Sheriff's Department.
Harris County Sheriff Adrian Garcia said a 17-year-old student was killed in an altercation at the school that began at about 7:10 a.m. CDT. Three other students were injured, including one who was airlifted in critical condition and two who suffered minor injuries.
Three people have been detained for questioning in connection with the stabbings and, according to Garcia, authorities have in custody those individuals think they need to have in custody.
Garcia said the investigation into the attack is ongoing and that police are still searching for the weapon(s) used in the attack as well as interviewing witnesses who saw the stabbings take place.
Police have not yet said what may have led to the violence.
KPRC-TV in Houston reported the school nurse contacted emergency crews and reported five stabbing victims and that the stabbing may have taken place inside the cafeteria.
Authorities said all of the victims in the stabbing were students in the Spring Independent School District. Spring High School is located about 20 miles north of Houston. Officials have not said when the school will reopen, though when it does, district officials said grief counselors will be made available to students and faculty.
District officials also said Wednesday morning that all campuses in the Spring ISD are under increased security while downplaying any connection to gang violence playing a role in the violence.
Wednesday's stabbing is the third mass-casualty event at a Houston-area school campus this year, though the first to include a fatality. In January, three people were wounded in a shooting on the Lone Star College North Harris campus. In April, 14 people were stabbed when a 20-year-old man used a razor utility knife to randomly stab and cut people at the Lone Star College's Cypress campus.
