GREAT MILLS, Md. (AP) - Authorities say the student who fatally shot a female classmate at a Maryland high school died from a self-inflicted gunshot wound during a confrontation with a school resource officer.
New details released by the St. Mary's County Sheriff's Office on Monday show that 17-year-old Austin Rollins fired one fatal shot to his head.
The sheriff's office says the school resource officer also fired his weapon, striking the gun in Rollins' hand.
The shooting occurred March 20 at Great Mills High School, which is about 65 miles southeast of Washington. A 16-year-old student, Jaelynn Willey, died after being taken off life support. Her funeral is scheduled for Friday. The sheriff's office said Rollins and the girl had been in a relationship that recently ended.
Desmond Barnes, 14, was shot in the thigh during the encounter. He was released from a hospital a day after the shooting.
Authorities released the 911 call he made after seeking shelter in a classroom.
According to the sheriff's office, Rollins entered the main entrance of the school the day of the shooting about five minutes before he shot Willey in the head with his father's gun. The same bullet traveled into the leg of Desmond Barnes, who had sought shelter in a classroom.
Rollins then turned a corner and passed several classrooms before the confrontation with the school resource officer, which occurred about three minutes after shooting Willey, the sheriff's office said. Rollins and Gaskill fired their weapons about 30 seconds later.
Gaskill, a six-year veteran with SWAT team training, was unharmed, reports CBS Baltimore.
In one of the 911 calls released, Barnes tells a dispatcher, "I was just shot in my school."
