There is an active shooter situation at a high school in Alpine, Texas, according to a sheriff in Brewster County.
TV station Fox 24 said that at least one person was killed.
Ruth Hucke, a spokeswoman for Big Bend Regional Medical Center in Alpine, said hospital personnel were tending to three "victims."
Hucke declined to say how the victims were injured or further identify them. When asked if the victims had been shot, Hucke said she "can't say anything further."
Hucke said the hospital would provide a statement later Thursday. She had no additional details.
Police said schools have been locked down amid the search for the shooter(s). They now believe there may be two active shooters.
The police didn't immediately provide additional information, other than the person was a male.
