A new report reveals Paddock practiced shooting in the desert days before the Las Vegas massacre.

WSJ reports:

The gunman who killed 58 people here Sunday appears to have gone out to the desert to practice shooting two days before the massacre, according to a law-enforcement official familiar with the investigation. Investigators have uncovered video footage from a home-surveillance system that shows Stephen Paddock driving alone to an area on the outskirts of Mesquite, Nev. where locals go for target practice. The footage shows Paddock heading to the area on the Friday before the attack, the official said.

Las Vegas law enforcement told CBS that the numbers on the note found in the gunman’s hotel suite were aiming calculations.

Officer Dave Newton from the Las Vegas Police Department’s K-9 unit said he noticed a note on the shooter’s bed stand once officers breached the room. He said the note was located near one of the windows that Paddock had smashed with a hammer to fire onto the crowd below with high-powered semi-automatic rifles outfitted to increase their rate of fire. “I could see on it he had written the distance, the elevation he was on, the drop of what his bullet was gonna be for for the crowd,” Newton said. “So he had had that written down and figured out so he would know where to shoot to hit his targets from there.”

Paddock’s mental health has been under the microscope since the shooting investigation was launched. A new report details the sexual fantasies Paddock engaged in, according to a Las Vegas prostitute he hired.
