A teacher who was injured during last Thursday's school shooting in Bend, Oregon, said she tried to shut a classroom door before pretending to be dead in the hope that the gunman would not target her again.

Becky Drury made the remarks in a statement released to the media on Wednesday, as the Bend Police Department confirmed that the firearm used in the attack on Silver Rail Elementary, which left three children and one teacher dead, was "purchased legally."

"Here is what I remember: Once I realized something was happening outside, I ran to see what was going on. I then saw the shooter and immediately ran back into the classroom. I turned to shut the door behind me, but the shooter was already there. Before I could do anything more, he shot me at close range and I fell to the ground," Drury said.

"Lying on the floor, I saw that my left hand was almost completely severed from the gunshot, and my other arm was also severely injured. I could not get up, defend myself, or protect anyone else," she added. "So, I did the only thing I could do, which was to pretend to be dead in the hope he would not shoot me again."

Drury continued, "What happened in that classroom was unimaginable, and like so many in this community, my heart is broken for everyone affected by this tragedy," and her "thoughts are with those who were hurt, those we lost, their families, our school, and the Bend community."

The Bend Police Department said on Wednesday that detectives are continuing a "complex investigation."

"They have served search warrants at the shooting suspect's home, as well as on his electronic devices and his social media accounts on a variety of platforms. That work continues, and it takes time," the department said in a statement.

Officials have disclosed the causes of death for three festivalgoers at this year's Burning Man event in Nevada, weeks after the annual gathering was rocked by multiple fatalities.

The causes of death ranged from cardiovascular disease to drug toxicity, according to local outlet KOLO 8 News, citing information from the Washoe County Regional Medical Examiner's Office.

Burning Man, held annually in Nevada's Black Rock Desert, ran from Aug. 30 through Sept. 7 this year, with all three deaths occurring during the festival.

His cause of death was determined to be hypertensive and atherosclerotic cardiovascular disease.

Another man, 51, of Truckee, California, died in an ambulance on Sept. 4 after experiencing chest pain at the festival.

"The deaths of three Burning Man participants in 2026 all appear to be from natural causes, but we defer to the medical examiner for official determinations," the organization said.

"We encourage and ask that people focus on the contributions of the individuals lost and avoid speculation about the circumstances of their passing out of respect for the participants and their families."
