In the days and months before he shot concertgoers from his high-rise hotel suite, gunman Stephen Paddock rented rooms overlooking two other music festivals in Las Vegas and Chicago, authorities said.

They gave no details on what his intentions might have been.

Meanwhile, the girlfriend of the man who shot and killed at least 58 people and injured more than 500 others in Las Vegas broke her silence.

The disclosures came as investigators struggled for a fourth day to explain what led the 64-year-old high-stakes gambler to open fire Sunday night on an open-air country music festival from the 32nd floor of the Mandalay Bay hotel casino. He eventually took his own life.

In August, Paddock booked a room at Chicago’s Blackstone Hotel that overlooked the park where the Lollapalooza music festival was held that weekend, a law enforcement official said.

The official said no evidence has been found that Paddock ever came to Chicago that weekend. Lollapalooza draws hundreds of thousands of music fans every year to Grant Park.

Also, the weekend before the Las Vegas bloodbath, Paddock had rented a high-rise condo in a Las Vegas building that overlooked the Life is Beautiful alternative music festival, Sheriff Joseph Lombardo said.

Girlfriend Marilou Danley talks about what happened

Marilou Danley's attorney read a statement on her behalf, where she stated she did not know Stephen Craig Paddock was planning the act.

"It never occurred to me in any way whatsoever that he was planning violence against anyone," said Matt Lombard, Danley's attorney, as he read her words.

The FBI is still speaking with the 62-year-old Danley to find out what she may have known before the attack.

She returned to the U.S. from the Philippines Tuesday night.

Her attorney also says they are cooperating with investigators.

Analyzing Paddock’s computer, cellphone and other electronic devices, investigators have found no obvious ideological motive, no clear connection to extremists or activist groups or outward display of mental illness.

The 64-year-old Paddock wired $100,000 to the Philippines days before the shooting, said a U.S. official who was not authorized to speak publicly because of the continuing investigation. Investigators are trying to trace that money.

Danley, who was overseas for more than two weeks, said she was initially pleased when she was wired money from Paddock to buy a house for her family in the Philippines. But she later feared it was a way to break up with her.

She said she loved Paddock as a “kind, caring, quiet man” and hoped they would have a future together. She also expressed she was devastated by the carnage and would cooperate with authorities as they struggle to get inside Paddock’s mind.

Also on Wednesday, President Donald Trump visited Las Vegas for the first time since Sunday night's mass shooting.

He also had a message for the survivors and victims' families.

"We will endure the pain together, and we will overcome together as Americans," he said.

The president visited with survivors, first responders and police officers.
