According to Galveston County Sheriff Henry Trochesset the gunfire in the school lasted a half an hour. During that time, police were engaged in a shootout with the gunman for 25 minutes, according to authorities.
When the gunfire finally ceased, the gunman was alive while eight students and two teachers were killed. On Monday, Trochesset told CNN that officers arrived quickly and engaged the shooter in the school’s art lab section just four minutes from the time of the first shot.
After laying out the timeline, Trochesset made a damning admission. According to the report from CNN:
But it’s unclear whether all the victims were shot by the suspect, or whether some were shot by deputies during the crossfire. Trochesset said authorities are waiting for the medical examiner’s autopsies to make that determination.
A “decent amount of cameras in the school” will help investigators piece together a timeline, Trochesset said.
