Mesa Grande Elementary School was locked down briefly Wednesday morning, after a neighbor apparently fired several shots into the air.


While parents were dropping off students at the Third Avenue campus around 8 a.m., a male adult neighbor apparently stepped outside of his home and fired two rounds from a revolver. School officials called 911 and locked down the campus.


"The staff and students were awesome in their response to an announcement of a lockdown," Mesa Grande Principal Pamela Seeger said Wednesday morning. "This happened before school started and kids are normally playing outside at this time and when I announced that we were going in code red lockdown ... it was less than two minutes before kids were inside and locked down."


In a post-Columbine world, students have lockdown drills, just as their parents and grandparents practiced fire drills when they were in school. But this is the first time in the three years that Seeger has been principal that the school has had to issue a real lockdown announcement.


"Up to now, it's just been drills," she said.


San Bernardino County Sheriff's Department deputies and Hesperia Unified School District police responded. The shooter exited his residence, still armed with his revolver, saw the police, and went back inside, leaving the residence again without the revolver.


Deputies attempted to take him into custody, and the man arrested, and was subdued with a Taser.


No injuries were reported and the lockdown was lifted in less than 30 minutes.


Hesperia resident Stanley Thrasher, 56, was arrested on charges of being a felon in possession of a firearm, negligent discharge of a firearm and child endangerment and booked at West Valley Detention Center. A search warrant for his house was obtained, and inside, police reportedly found two revolvers, of .22 and .44 caliber.


Mesa Grande Elementary School has approximately 700 students.


Anyone with information about this case is asked to call Deputy Frank Hardin at 947-1549 or the anonymous WE-TIP line at 800-782-7463.
