The name of the suspect in custody is 17-year old Dimitrios Pagourtzis, reports CBS, citing law enforcement sources.

The gunman who allegedly opened fire at a high school in Texas on Friday morning has been identified.
Police sources told CBS News that the shooter is 17-year-old Dimitrios Pagourtzis. Police believe he is a student at Santa Fe High School. He allegedly began his shooting spree around 7:45 a.m., killing at least 10 people and wounding a dozen more — a majority of whom were students — on the school’s campus. Police said he was armed with an AR-15 style rifle, a pistol, a shotgun and pipe bombs.
The school was evacuated and the alleged shooter was taken into custody around 9 a.m. local time. A second person of interest, also believed to be a student at the school, was “detained and questioned,” Harris County Sheriff Ed Gonzalez said in a presser.
Explosive devices were also found at the school and off campus, but were not detonated, police said.
One student who spoke with HLN said that the shooter — who he knew from the school — walked into a friend’s classroom and opened fire on students, shooting one girl in the head. He claimed that the shooter was wearing a trench coat that had “USSR” written on the back. Other students said that the shooter started opening fire in an art classroom around 7:45 a.m.
