A 17-year-old high school student was arrested for possession of a firearm as Thunder Mountain High School and Riverbend Elementary School were in lockdown this morning.

Lt. David Campbell says a Juneau Police Department officer working at Thunder Mountain received a report from a student just after 10 a.m.

“A 17-year-old female told the officer that she saw a 17-year old male with a handgun. The 17-year-old male suspect was last seen leaving the school on foot,” Campbell says.

Other schools in the Mendenhall Valley and downtown’s Juneau-Douglas High School were in ‘stay put’ mode.

Juneau School District spokeswoman Kristin Bartlett explains the difference between lockdown and ‘stay put.’

“In a lockdown, all of the blinds are closed, and the lights go off, and students get into more of a hidden mode. And in a ‘stay put,’ that just means that we aren’t having outdoor recess and kids aren’t going between classes,” Bartlett says.

Lt. Campbell says the suspect was found near the Thunder Mountain around 10:30 a.m.

“[Juneau police] officers contacted the 17-year-old male suspect near the Dimond Field House. He was taken into custody and the .22-caliber pistol was seized as evidence,” Campbell says.

The teenager was arrested for fourth degree misconduct involving a weapon, a Class A misdemeanor. He was transported to the Johnson Youth Center.

The suspect’s name could not be released because of confidentiality laws.

The lockdowns were lifted around 10:40 a.m. and students at Thunder Mountain High School were allowed to come and go as usual.

No one was injured during the incident.

Bartlett says every school holds drills for a potential lockdown. The one at Thunder Mountain High School went according to plan.

“There have been real lockdowns here in the past. This is the first time that we’ve had an incident of this nature,” Bartlett says.

In the school’s administration offices, Juneau Police Department investigators interviewed at least two students and a parent as potential witnesses to the incident.

Bartlett says the district issued a phone message to all parents notifying them of the lockdown after it was lifted.
