Jesus Antonio "Toño" Hernandez Castro, 22, was supposed to have breakfast with his family on January 2, 2023. Instead, around 5:45 that morning, his roommate called 911 to say Toño had killed himself.

Officers at the converted garage apartment on the 3500 block of San Francisco Avenue in Las Vegas didn't believe it, and they called homicide. In questioning, police say the roommate, 24-year-old Jesus Mendoza-Zarate, changed his story several times. First he said he woke up and found Toño on the floor with a gun beside him. Then, when detectives pointed out the injuries on his elbows, shoulder and back and what looked like blood on his hands, he admitted they'd fought over his gun and said it went off by accident. He also admitted he waited an hour before calling 911. The coroner found Toño died of a gunshot wound to the neck.

Mendoza-Zarate was booked on open murder. An hour is a long time to wait. What do you think he was doing in that hour?
