Scott Bybee was the young man who committed suicide. His father Jay Bybee is a federal judge. Apparently he was plagued by depression for years and decided that he wanted to die in the temple.
I don't know if you' remember, but as you enter the lobby to the right of the recommend desk there is an atrium/courtyard. A lot of times the youth will spend time in this beautiful place while they wait to go down to do baptisms. The young man (who was wearing a gray suit) entered the lobby and went to the desk, requesting a set of scriptures. He then went into the atrium and sat down. He took out a teddy bear and a glass figurine and set them beside himself.
The Peccole Ranch ward youth were there waiting to do baptisms. Most of them had gone down to the baptismal font, but three girls stayed behind as they finished braiding each other's hair. They were wary of the young man, sitting ten feet away from them. They said he kept looking over at them, then looking down at his lap. The girls were distracted when they heard the gunshot. None of them witnessed the shooting.
Thinking it was a tree breaking in the atrium, they looked up and then around. The young man had fallen backwards into the bushes behind him. Hearing the bang,an adult came into the atrium and looked at the young man. Initially he assumed Scott had some sort of attack and had bitten his tongue because there was so little blood (he put the gun in his mouth), but then he noticed the handgun beside him. The police were already at the temple because he had called his parents to let them know that he was at the temple and he was going to kill himself so they were at the body within one minute.
A few miracles I've observed:
1) Those present, including the police couldn't believe how clean the scene was. The blood was extraordinarily contained and none of the temple workers, nor the young women saw any of the gruesome aftermath
2) The young women who were ten feet away when it happened didn't witness the shooting, and have remained extremely calm. The cousin of my friend initially felt like she should have approached the young man but was constrained by the spirit, and the adults in her life explained that due to his state of mind it was better that she didn't approach him.
3) We are all given agency, and that night Scott Bybee made the choice to take his life, but Heavenly Father protected those who didn't make that choice, who were in the temple with him. All involved have reported to have felt peace in a tragic situation.
This has been an extremely difficult week to think about. The Las Vegas temple is my most beloved temple. I've served in it nearly every month for over seven years. It is where I have come to learn so much about my Savior and I've had countless spiritual experiences that I could never forget. After the shooting I spent the next day listening to my "I Feel My Savior's Love" playlist trying to feel peace amid confusion. I was especially touched by the song I Feel My Savior's Love, particularly this part
"I feel my Savior's love; Its gentleness enfolds me,
