This was discussed in detail many years ago - with a fair bit of misinformation circulated. At the risk of angering members for regurgitating the details here is my summary compiled some time ago:
The Justin Smeja Shooting Incident - “Facts” as reported by the two eyewitnesses (they agreed in all salient respects when interviewed separately) – summarized from a variety of sources the most trustworthy to be, in my opinion, Ro Sahebi’s 2013 movie “Dead Bigfoot: A True Story” (resulting from Smeja’s desire to tell his story on camera)
Occurred October 8, 2010.
Smeja and an anonymous friend, both from Sacramento, were bear hunting in the Sierra Nevada near Gold Lake in Plumas County, California. Gold Lake is about 5.5 miles SW of Graeagle, about 10 miles N of Sierra City, about 45 miles NW of Lake Tahoe, about 50 miles W of Reno, Nevada, and about 90 miles NE of Sacramento.
Smeja’s friend was driving his truck, with Smeja in the passenger seat, down a dirt road removed some distance from the nearest well-travelled road through a forested area.
They were passing through a meadow expecting to see a bear, if they were to see any wildlife.
Just ahead of them about 80 yards off the road to their right (the passenger side) they spotted a dark hair covered animal.
They estimated it to be about 7 feet tall – it stood upright and stood and walked like a human.
Smeja’s friend stopped his truck and picked up his binoculars. Smeja picked up his scoped rifle (a 25-.06), opened the passenger side door, placed his right foot on the ground, rested the rifle on the car door (window was down), and placed the crosshairs on the animal for 6-7 seconds.
Smeja’s friend was telling Smeja in ever more forceful tone: “Bro, don’t shoot. Hey Bro, no! Hey, hey, hey, hey!”
Smeja is thinking this animal is out of place; this animal should not be there (his words “this ain’t right”).
The animal was standing at the edge of the clearing waving its arms over its head and taking a couple of slow steps toward the truck.
Smeja had the crosshairs trained center mass (center high chest) and was squeezing the trigger as the animal started to turn to its left.
The gun discharged and impact was positioned just below the right armpit (the driver witnessed the concussion of the shot through his binoculars).
The animal stumbled a couple of steps, dropped to all 4’s, and began scrambling quickly over a hill. Smeja had racked another bullet, considered firing a shot up the animal’s A$$ (Smeja’s words), but didn’t, as the driver was yelling: “No way!”
As the two humans departed the truck to chase the adult animal to verify the kill, they encountered two young animals at close range.
The young animals were searching for their parent – sometimes separating, sometimes rejoining, and vocalizing to one another.
Smeja decided to shoot one of the little ones with his chambered round – intending to take a dead little one with them back to civil1zation.
Smeja shot it below its chin in the neck just above the chest. It rolled down the hill and landed on Smeja’s right boot.
Smeja picked it up and looked right into its eyes as it died in his arms. Smeja said at that moment he realized he had murdered a little kid. He said it was human – not an ape – a little human kid.
Smeja said he was not thinking rationally. He thought he had just committed murder.
He buried it under some brush intending to return the next day to retrieve it but failed to do so – not returning until Spring 2011 and not finding the body (he found a piece of hair and hide in the general area – DNA testing later determined that to be bear).
