New surveillance video that recorded a deadly 2014 university shooting in Seattle has been released and shows the fearless actions of a student who took down the gunman.
The King County Prosecuting Attorney’s office released 21 campus security videos on Tuesday, which show 26-year-old Aaron Ybarra entering Seattle Pacific University with a gun in June 2014, where he killed one student and injured three others.

The videos were made public following a court appeal filed by several local Seattle media outlets.
The video shows Ybarra, who struggled with mental illness and had stopped taking his medication at the time of the incident, enter the building wielding a long gun and pointing it directly at a student studying near the entrance.

In the video, it doesn’t appear Ybarra fires the gun until student Sarah Williams comes down a flight of stairs and is shot.
Williams can be seen standing in shock when student safety monitor Jon Meis comes to her aid.
According to Meis, Ybarra attempted to reload when his gun became jammed following the initial shot.
“I could see he was fumbling so I took my pepper spray gun … sprayed him in the face with it,” Meis told police during an interview in 2014.
The new video then shows Meis lunging at Ybarra, tackling him to the ground.
Meis can be seen stripping the weapon away from Ybarra and running for safety.
But just seconds later Meis returns and notices Ybarra pulling out a hunting knife.
The student security monitor jumps on the attacker again, disarming Ybarra for a second time.
“I had to give that security guy props,” Ybarra told police in 2014. “He was pretty brave.”
Others cameras from inside the building show students with their hands on their heads being evacuated from the building by police.
KIRO 7, one of the local media outlets that fought to have the videos released, wrote that they were “reviewing” the material to find out “what can be learned to enhance public safety.”

Paul Lee, 19, was killed in the incident. Video showing the moment of his death was not released.
Ybarra told detectives following the 2014 incident that he hoped to carry out a murder-suicide.
Ybarra was charged with one count of first-degree murder, two counts of attempted murder and one count of second-degree assault.
The accused is scheduled to be tried in September.
In the two years since the university shooting, there have been more than 700 mass shooting in the U.S.
