Gunman Stephen Paddock was an accountant who played $100-a-hand-poker

LAS VEGAS (CNN) Stephen Paddock, the man police say killed at least 58 people on the Las Vegas Strip, was a retired accountant who enjoyed playing $100-a-hand poker, his brother says.

Eric Paddock of Orlando, Florida, also told CNN their father was a bank robber.

Authorities say Stephen Paddock, 64, lived within easy driving distance of Las Vegas, had a pilot’s license and had legally purchased some guns.

But investigators haven’t determined a motive for the Sunday night shooting.

Here’s what we know so far about the man responsible for the deadliest mass shooting in modern US history.

Family stunned

Eric Paddock told CNN on Monday his brother had worked as an accountant and had plenty of money.

“He was a wealthy guy playing video poker… on cruises,” he said, adding that his brother could afford anything he wanted and played $100-a-hand poker.

Their father was a well-known bank robber and at one point was on the FBI’s 10 most wanted list, he said. Their father died a few years ago.

Stephen Paddock had been married in the past and lived with his girlfriend, Eric Paddock said, but he didn’t know of any children.

Stephen last communicated with his brother via a text, asking Eric about their mother, who’d lost power during Hurricane Irma. Eric also said Stephen spoke to his mother on the phone a week or two ago.

He has no idea why his brother would kill anybody. The family found out about the shooting at 1 a.m., when police called.

“He was my brother and it’s like an asteroid fell out of the sky,” Eric Paddock said.

Kept a low profile

Stephen Paddock had been living in Mesquite, 80 miles northeast of Las Vegas. The town of 18,000 people is a retiree community with several casinos and golf courses.

Authorities searched his home Monday and found weapons and ammunition, but Mesquite police spokesman Quinn Averett did not give details.

“What’s unique for us is the gunman, the shooter, and the person with him, we in the Mesquite Police Department have not had any contact with these people in the past. We haven’t had any traffic stops, any law enforcement contact, no arrests or nothing,” Averett said.

Eric Paddock told CNN he helped move his brother from Melbourne, Florida, to Mesquite about a year ago.

Law enforcement has no “derogatory information” about Stephen Paddock, besides the fact that he received a citation several years ago that was handled in the court system, Las Vegas Metropolitan Police Sheriff Joseph Lombardo said.

“We had no knowledge of this individual,” Lombardo said. “I don’t know how it could have been prevented.”

The hotel

Paddock had been staying at the Mandalay Bay Resort and Casino in Las Vegas since last Thursday. Authorities said it appears he fired guns from his 32nd floor room into the crowd at the Route 91 Harvest music festival on Sunday night, killing at least 58 people. More than 500 others were hurt in the shooting and subsequent stampede.

Authorities believe Paddock had a device similar to a hammer to smash the hotel windows prior to the shooting, Lombardo said.

Officials think Paddock brought the weapons into the hotel by himself but did not provide specifics.

Hotel employees had been in the his room prior to the shooting but did not notice anything amiss, Lombardo said.

His guns

Paddock had bought multiple firearms in the past, several of them purchased in California, a law enforcement official told CNN. But those don’t appear to be among the 10 or more guns found in the Mandalay Bay hotel room.

The suspicion, based on initial reports, is that any of the rifles used were altered to function as an automatic weapon, the official said. Among the weapons found were a .223 caliber and a .308 caliber.

So far investigators believe the firearms were purchased legally.

Eric Paddock said he knew his brother had a couple of handguns and maybe one long rifle but did not know of any automatic weapons.

Stephen Paddock did not have a machine gun when he moved him from Melbourne to Mesquite, Eric Paddock said.

Seeking a motive

Lombardo said authorities have found no connections between Paddock and any terror groups.

“We have to establish what his motivation was first,” Lombardo said. “There’s motivating factors associated with terrorism other than a distraught person just intending to cause mass casualties. Before we label with that, it’ll be a matter of process.”

It appears he acted alone, Lombardo said.

She lived with suspect

Marilou Danley was identified as Paddock’s companion or roommate, Lombardo said.

She does not appear to have been involved in the shooting and was in the Philippines when the shooting took place, authorities said. Paddock had been using some of her identification, Lombardo said.

Had pilot’s license

The suspect had a pilot’s license but he was not up to date on his medical certification which he would need in order to fly legally, a federal official said.

The FAA website shows that the last time he went to get the medical certification required for private pilots who want to fly was February 2008 so he could not have flown legally recently.

The FAA will not release any information regarding his mental health from his last certification in 2008 because it is protected under federal privacy rules.

So far, authorities have found no military records for Stephen Paddock.
