Staff Writer

Officials say at least three people are being treated for gunshot wounds and two people have been detained following a shooting at a high school near Houston.
Harris County Sheriff Ed Gonzalez tweeted Friday that one person is in custody and a second person has been detained following the Friday morning shooting at Santa Fe High School.
Gonzalez says a police officer was injured but the extent of the officer's injuries is unknown.
Gonzalez says there are "multiple casualties" but didn't elaborate. Houston-area media have cited unnamed law enforcement officials saying there were fatalities. The Associated Press has not been able to confirm the reports.
Dr. David Marshall is chief nursing officer at the University of Texas Medical Branch in Galveston. He says one man was undergoing surgery at the hospital Friday morning following the shooting. He says a juvenile has been admitted and a second adult is being treated in the emergency room.
