Law enforcement officials claimed that a handwritten note, found in a hotel room of the Las Vegas murderer, contained mathematical calculations used to determine the distance and trajectory from his 32nd-floor window to the mob of concertgoers he targeted below, CNN reported.

Officials found the note among various weapons when they broke into the hotel room right after the incident happened on October 1. The murderer, Stephen Paddock reportedly committed suicide before officers opened the door. That evening, 58 people were killed, and almost 500 others were injured.

What officials found out about the shooter

The investigation about Paddock's motive is still ongoing. Paddock, a 64-year-old retired accountant, and a gambler had been buying lots of high-powered weapons for several years before the crime. Paddock had no criminal record before the attack. The collected details evidenced that he had planned the attack very carefully.

On October 6, Undersheriff Kevin C. McMahill stated that the crime was not connected with terrorism or Islamic State. He noted that Paddock was the only shooter in the room, but there was a possibility that someone else knew about his plan. It was still unclear why Paddock left 50 rounds of explosives in his vehicle, which was found in the hotel parking lot, and why he bought them.

McMahill added that Paddock was going to escape after the attack, and there was no information if he intended to use the materials for bomb-making.

On October 4, Vice President Mike Pence visited Las Vegas. He emphasized the first responders' efforts and noted that "Their actions undoubtedly saved lives that night."

Victim's relatives asked officials to control Paddock's assets

On Friday, the relatives of one of the victims, John Phippen, filed a petition to a Nevada court asking for appointing a special public administrator to control the murderer's assets and estate.

Paddock was a real estate investor. He bought a house for $369,022 three years ago in Nevada.

The petition was aimed at making Paddock's property available for further possible lawsuits filed by the victims of the Las Vegas tragedy, Fox2Now reported. A California attorney Richard A. Patterson claimed that the court “will notify (Paddock’s) family members, and we’ll see where this goes.”

John Phippen, 56, attended the festival with his son. During the shooting, they both were helping other people. Phippen was shot dead by Paddock when he was shielding a woman
