In newly released body camera footage, two Las Vegas police officers can be seen holding their position in a hallway one floor beneath the Oct. 1 gunman as rounds are continually fired into the concert crowd below.

“Oh, my God,” Las Vegas police officer Cordell Hendrex says on the video about four minutes after he and his trainee, Elif Varsin, first arrive on the 31st floor of Mandalay Bay in the middle of the mass shooting. The exclamation was in reaction to hearing more rapid gunfire just above them.

Still the pair hold their position, standing alongside three armed Mandalay Bay security guards.

Prosecutors charge Arizona man who sold ammo to Las Vegas shooter
 
Prosecutors charge Arizona man who sold ammo to Las Vegas shooter

Federal prosecutors in Nevada have charged Arizona resident Douglas Haig with conspiracy to manufacture and sell armor-piercing ammunition. According to a statement from the U.S. attorney’s office in Las Vegas, Haig appeared Friday afternoon before U.S. Magistrate Judge Michelle Burns in Phoenix and was released on bond pending a Feb. 15 status conference there. If convicted, Haig could face up to five years in prison. A criminal complaint filed Friday morning is sealed in Nevada, but it appears in Arizona court records. According to the document, the FBI has determined that “two unfired cartridges bearing Haig’s fingerprints” were found in gunman Stephen Paddock’s suite at Mandalay Bay. At a news conference Friday at his lawyer’s office, Haig said Paddock demonstrated no unusual behavior when he came to Haig’s home in Mesa to purchase approximately 720 rounds of tracer ammunition. “Business records reveal that Haig sold armor piercing ammunition throughout the U.S., including Nevada, Texas, Virginia, Wyoming, and South Carolina,” according to the U.S. attorney’s office.

A Las Vegas police sergeant has confirmed that Oct. 1 gunman Stephen Paddock was dead before any officers breached his Mandalay Bay suite. A document unsealed Tuesday seemed to contradict that, stating that “as SWAT officers breached room 135, they observed Stephen Paddock place a gun to his head and fire one round.” The sergeant who helped author the preliminary report said it became clear as the investigation unfolded that none of the officers saw the gunman shoot himself. Clark County Sheriff Joe Lombardo reaffirmed those details in a news conference the day the police report was released.
