The gunman who opened fire at a Las Vegas concert has been identified as 64-year-old Stephen Paddock.

Here's what we know so far:

• Paddock killed himself before officers reached him on the 32nd floor of the Mandalay Bay Resort and Casino, where police said he opened fire on the Route 91 Harvest Music Festival across the street.

• At least 10 guns were found in his room, including several rifles.

• Police believe Paddock had been staying at the hotel since Thursday. Employees who had been in his room had not noticed anything suspicious, the sheriff said.

• Authorities did not provide any motive for the killings.

• Clark County Sheriff Joe Lombardo said he did not know the "belief system" of Paddock.

• Special agent in charge of the FBI's field office in Las Vegas, Aaron Rouse, said federal authorities had found no evidence or "connection to an international terrorist group."

• Paddock was a resident of Mesquite, Nev.

• He worked as an accountant, according to ABC, and public records show that he has both a pilot's and hunting license.

• Las Vegas police also had nothing more than a routine traffic violation on Paddock, according to Kevin McMahill, the department's undersheriff.

• Worked from 1985 to 1988 for a company that is now part of Lockheed Martin.

• Authorities searched Paddock's home Monday morning, finding guns and ammunition, said Quinn Averett, a spokesman for the Mesquite police.

• He held additional property in northern Nevada that would be searched later Monday, Las Vegas police said.

• Police sent out alerts looking for a "companion" of Paddock, 62-year-old Marilou Danley, as a person of interest, but later called off after officers determined that she was not part of the attack. Danley was out of the country.
