Update VI: In an afternoon press conference, Texas Gov. Greg Abbott revealed more details about today's school shooting in Santa Fe, Texas.

The shooter, 17-year-old Dimitrious Pagourtzis, used a sawed-off shotgun and a .38 revolver in the attack. Both weapons belonged to his father.

He also filled the world in on some of the shooter's odd behavior. For example, Pagourtzis, pitured above, wore a trench coat to school every day even when it was 90-plus degrees. He was also picked on by the school's coaches.

According to information contained in his journals, on his computer, and on his cell phone, the shooter said he wanted to to commit suicide after the attack. Instead, he gave himself up and is currently at the Santa Fe Police Department.

The final death toll? 10 dead, 10 injured.

Update V: The name of the shooter has been released: He is 17-year-old Santa Fe student Dimitrios Pagourtzis. The suspect is in custody after killing as many as 10 people and wounding more than a dozen others.

CNN shared a screenshot of the shooter's Facebook page before it was taken down:

According to Cassandra Fairbanks, Dimitrios Pagourtzis was a "Columbiner": he had the same button that Dylan Klebold wore on his shoe during the columbine massacre.

The Daily Caller reported that social media pages that purport to belong to Pagourtzis reveal that he was obsessed with guns, knives and animal torture. They also showed that he owned a trench coat with USSR and Nazi medals on it (the jacket can be seen in the photo above). His Facebook page also appeared to suggest an obsession with Satanism.

Photos from his Instagram account appeared to show a collection of guns and knives.

A local television station described Pagourtzis' family as a Greek family that typically kept to themselves. Neighbors said they had not seen the shooter recently.

Two students said the Santa Fe shooter was wearing a black trench coat and had a sawed-off shotgun.

One local hospital said it received eight patients, six of whom had been discharged. One of the others was in critical condition, another was in fair condition. The victims were all high school students.

A second suspect has been detained, but it's unclear if they are still in custody.

According to Wikipedia, this is the 20th school shooting in the US so far this year.

Update: Federal Law enforcement officials told a local TV station that there are at least eight people dead following the Friday morning shooting at Santa Fe High School in Santa Fe, Texas. The total number of fatalities could be as high as 10.

According to CNN, the shooting took place one day before the school's graduation ceremony, which is set for Saturday.

Earlier, we picked up reports that at least one student had been shot in the leg, and was receiving medical attention.

One student who spoke with reporters described Friday as a day like any other. Until somebody pulled a fire alarm and students started lining up outside per the fire drill protocol.

Then suddenly gunshots rang out.

"So, it was just a normal-like class day. We all were doing our work in first period. And then all of a sudden like it's a fire drill," 14-year-old junior Angelica Martinez said.

"Not even five minutes later, we start hearing gunshots."

That's when everybody starts running, she said, despite teachers telling them to "stay put."

"But we're all just running away."

Myles Kanipes, son of Sante Fe High School athletic director and football team head coach Mark Kanipes, told CNN that his dad is on lockdown on campus, but is otherwise safe.

"He is fine but he said it’s crazy (right now) but would call me once he finds out more. All I know is someone pulled the fire alarm and once everyone got out the classes someone started shooting. His secretary is the one who first heard the shooting, the shooter was in the art class," Myles Kanipes said.

After the shooting started, a group of students were directed to empty their backpacks in a field.

Meanwhile, at least three helicopters were seen waiting in the school's parking lot.

The shooting suspect, who is rumored to be a white male according to earlier reports and has also been confirmed to be a student, is now in custody.

A Santa Fe, Texas High School is on lockdown after an active shooter has been reported on campus. One student told local media that she saw a gunman shoot a female student, but that has so far been unconfirmed.

Santa Fe Police, the Galveston County Sheriff's Office and other agencies are responding to the scene.

Sophomore Leila Butler told ABC13 that at about 7:45 am fire alarms went off and students left their classrooms. Some students believe they've heard shots fired. She is currently sheltering with other students and teachers near campus.

Police were called to the school on 16000 Highway 6. Students were seen being lined up outside.

Santa Fe is a small city just south of Houston.
