BEND, OR -- The Deschutes County District Attorney's office released video, Wednesday, of the recent attack on a woman at the High Desert Museum. A museum visitor captured the video on her cell phone.

The victim, now identified as 39-year-old museum employee Amanda Berry, can be heard saying, "You're hurting me ... please let me go. Don't do this." Also on the recording, patrons try to intervene, saying, "Hey! Slow down;" "He has her in a choke hold," and "He's going to hurt her." D.A. John Hummel says four bystanders approached the suspect at great personal risk to themselves. He says their actions resulted in Berry's release.

Oregon State Police Trooper Richard Brannin, from OSP's Bend office, arrived at the museum and saw 36-year-old Nicholas Berger with a knife. The encounter ended with Trooper Brannin shooting Berger, who died at the scene. 

The D.A.'s office also released dispatch audio, Wednesday, from the Deschutes County Sheriff's Office and OSP. Click HERE to access the D.A.'s YouTube channel. The Major Crimes Team continues to investigate whether the shooting was justified.
