The video from the Sept. 6 assault that shook Nevada’s capital city was a snippet of a 4-minute presentation that was shown this week at a meeting of the Nevada Sheriffs and Chiefs Association in Las Vegas.
A camera at a casino across the street from the IHOP shows Eduardo Sencion running through the parking lot, firing bullets in rapid bursts. At one point, the 32-year-old shoots at a woman standing by a motorcycle at close range.
Authorities said the woman was saved by her helmet.
The video was first reported by the Nevada Appeal. The Associated Press obtained a copy Friday.
Crime scene photos included with the presentation detailed the horrors inside the restaurant, from a bullet hole in a glass partition to carpet stained with the victims’ blood. The presentation’s audio conveyed witnesses’ frantic calls to 911.
The video shows Sencion shuffling around cars in the parking lot as he repeatedly squeezes the trigger of his AK-47, which had been illegally converted into a fully automatic weapon.
Another angle from a surveillance camera inside a nearby business shows a woman running past a door and ducking down to get out of harm’s way.
Investigators said Sencion fired 79 rounds, killing four people — three members of the Nevada National Guard who were having breakfast and a woman who was dining with her husband.
Killed were Sgt. 1st Class Miranda McElhiney, 31; Sgt. 1st Class Christian Riege, 38; Maj. Heath Kelly, 35; and Florence Donovan-Gunderson, 67.
Two other Guard members — Sgt. 1st Class Jeremiah Mock, 32, and Sgt. Cait Kelley, 25, were among seven people who were injured.
The rampage ended 85 seconds after it began, when Sencion shot himself in the head and died in the parking lot.
Authorities said Sencion was diagnosed with paranoid schizophrenia as a teenager. In the days and weeks leading up to the shooting, it was as if he was fearful of himself and what he might do.
Family members said he became increasingly withdrawn, and said he avoided relationships because he was afraid “he would father a child and pass along his illness.”
He immersed himself in the Bible, and gave his mother keys to his gun safe, warning her he was “getting sick.”
