Sheriff Gonzalez said that the campus - about 30 miles (48 km) southeast of Houston - is still considered an active crime scene.
Explosive devices had also been found at the school and off campus, Gonzalez tweeted. “Law enforcement is in the process of rendering them safe. School has been evacuated.”
Authorities found writings in the Texas shooting suspect's journals that indicated he wanted to take his own life, Texas Govenor Greg Abbott said.
"We also know information already that the shooter has information contained in journals on his computer and his cell phone that he said that not only did he want to commit the shooting, but he wanted to commit suicide after the shooting," he said.
"As you probably know, he gave himself up and admitted at the time he didn't have the courage to commit the suicide, that he wanted to take his own life earlier," Abbott added.
Mr Abbott called the shooting "one of the most heinous attacks that we've ever seen in the history of Texas schools." He added that the weapons used were a shotgun and a .38 revolver.
He said explosive devices including a Molotov cocktail that had been found in the suspected shooter's home and a vehicle as well as around the school and nearby.
Mr Abbott said there are "one or two" other people of interest being interviewed about the shooting.
President Donald Trump called the shooting heartbreaking and said that federal and local authorities were coordinating in the wake of the gun attack.
“My administration is determined to do everything in our power to protect our students, secure our schools and to keep weapons out of the hands of those who pose a threat to themselves and to others,” Mr Trump said at the White House.
Student Leila Butler told the local ABC affiliate that fire alarms went off at about 7.45am local time and students left their classrooms. She said some students believe they heard shots fired, and that she was sheltering with other students and teachers near campus.
Another student, Dakota Shrader, told Fox 26 TV her 17-year-old girlfriend told her by phone that she was wounded but was recovering in a hospital. "My friend got injured," said an emotional Shrader. "Her leg, she got shot in the leg."
Dr David Marshall, chief nursing officer at the University of Texas Medical Branch, said that the hospital was treating at least three patients - two adults and one person under 18. He said it was not immediately clear if that child was a student.
"I know that they have gunshot wounds but that's the extent of the knowledge I have at this point," Marshall told reporters at a news conference. "One adult is in our operating room."
Texas Attorney General Ken Paxton issued a statement on the shooting: "The thoughts and prayers of all Texans are with the people of Santa Fe and those affected by today's tragic shooting. As horrific reports come out of Santa Fe High School, my office stands ready to assist local law enforcement as needed."
