Sheriff: Great Mills School Shooter Died From Self-Inflicted Gunshot Wound

BALTIMORE (WJZ) -- The teen accused of opening fire inside Great Mills High School last week shot himself in the head, officials said Monday. Authorities also announced the gunman's moves were captured on surveillance video.

A new timeline from the St. Mary's County Sheriff's Office has revealed horrific details as the scene unfolded at Great Mills High School last week.

Students called 911 to report the shooting on March 20.

The sheriff's office says 17-year-old Austin Rollins pulled into the parking lot around 7:50 a.m. Two minutes later, the teen walked through the school's main entrance. Five minutes after that, investigators say the suspect found 16-year-old Jaelynn Willey in a hallway, approached and shot her in the head.

Just minutes later, Deputy 1st Class Blaine Gaskill confronted the shooter. Investigators say that's when Rollins shot himself in the head. Gaskill simultaneously fired a shot that hit the gun that Rollins was holding.

Gaskill, a six-year veteran with SWAT team training, was unharmed.

The sheriff's office said Willey had a relationship with Rollins that had recently ended.

Two days after the shooting, her parents took her off life support.

"My daughter was hurt by a boy who shot her in the head and took everything from our lives," Melissa Willey said.

Her family participated in a peace rally Sunday.

Desmond Barnes' mother, Kimberly Dennis, was also present.

Investigators say the same bullet that hit Willey ricocheted and struck the 14-year-old in the leg, but he survived.

"We truly have felt the prayers and there is nothing like feeling you all's prayers and your loving arms around us," Dennis said.

Investigators say Rollins used his father's legally owned Glock handgun in the attack.

A funeral will be held Friday for Willey in Hollywood, Maryland.
