UPDATE: Monday Oct. 3, 2017, 10:45 a.m. EDT —

The death toll has risen to 58 for the shooting, with 527 people injured. Police are still looking for a motive for why Stephen Craig Paddock undertook the shooting. Police found 23 guns in Paddock's hotel, mostly rifles and a pistol, and an additional 19 firearms and explosives at his house with thousands of rounds of ammunition. The hotel room had rifles on tripods and police believe maybe one of the rifles was modified to make it shoot faster. Paddock shot at security guards before SWAT teams broke into his room on the 32nd floor room at the Mandalay Bay Hotel. SWAT teams, however, found him dead once they got in.

ISIS claimed responsibility for the attack, but there is no evidence to back up their claim, and law enforcment is skeptical.

Stephen Craig Paddock was a retired accountant with plenty of money, according to his brother. Police said that they had no prior knowledge of Paddock nor any issues with him. He had purchased guns legally in the past, but it is not yet known if they were among the ten or more guns found in his hotel. Investigators have not yet established a motive.

Marilou Danley lived with Paddock, who kept a relatively low profile.

Original Story:

Stephen Craig Paddock is the 64-year-old white man who is the suspected shooter in the mass killing in Las Vegas Sunday night.

The gunman opened fire on a country music concert from across the street at the Mandalay Bay Hotel. Police stormed his room on the 32nd floor of the hotel. Paddock had killed himself by the time police had gotten in, according to the Associated Press. At least eight guns, including long guns, were found in the room, according to CNN.

At least 50 were killed and 200 injured in what is the deadliest mass shooting in U.S. history. It surpassed the last deadliest shooting, which occurred last year at an Orlando, Florida, nightclub. Forty-nine people were killed.

Police believe Paddock acted alone. He was from Mesquite, Nevada, which is located around 80 miles away from Las Vegas.

Paddock was traveling with a female companion, Marilou Danley, that police had asked for the public’s assistance in finding her, before tweeting out this morning that they“located the female person of interest.”

There were approximately 22,000 concert goers at the Route 91 Harvest Festival when the shooting took place. Country singer Jason Aldean was performing. More than 400 people were taken to area hospitals, according to Las Vegas Police. Two Las Vegas police were injured in the incident, and one off-duty officer was killed who was attending the concert. His name is being withheld until his family can be reached and notified.

Police are still investigating both Paddock and the incident.
