Law Enforcement officials say they believe US mass murderer Stephen Paddock acted alone during the rampage in Las Vegas, Nevada, last week that killed 58 people and wounded 489 others, the deadliest mass shooting in US history.
Kevin McMahill, the undersheriff for Clark County, which includes Las Vegas, said Saturday that investigators are still trying to determine the shooter’s motive.
“We still do not have a clear motive or reason why,” a frustrated McMahill said. “We have looked at literally everything.”
Federal and local investigators have followed 1,000 leads and examined Paddock’s political views, finances, social behavior and any possible radicalization.
“We have been down each and every one of these paths,” McMahill said. “We all want answers.”
The FBI has announced that it plans to erect billboards in Las Vegas asking for information about the killer.
“If you know something, say something,” said Aaron Rouse, agent in charge of the FBI office in Las Vegas. “We will not stop until we have the truth.”
Paddock, 64, rained down a barrage of bullets from the 32nd floor of the Mandalay Bay Hotel towards an open-air concert Sunday night. He was found dead inside his hotel room from a self-inflicted gunshot wound to the head
The shooting was the deadliest mass shooting by a lone gunman in US history and the worst mass murder since the terrorist attacks on September 11, 2001.
In a televised address the following day, US President Donald Trump offered his “warmest condolences” for the victims of the mass shooting, but did not address the scourge of gun violence that has become a common occurrence in the country.
Paddock, like the majority of mass shooters in the US, was a white male. Critics say being white in the US somehow protects an individual from being labeled a terrorist.
Some law enforcement officials increasingly believe Paddock had a severe mental illness that was likely undiagnosed.
The picture that is emerging of the shooter is of a man that had real difficulty interacting with people, despite being financially successful, ABC News reported Saturday, citing sources familiar with the shooting investigation.
He is described as being unfriendly, disconnected and had difficulty establishing and maintaining meaningful relationships.
He was also known for playing gambling games in casinos for hours at a time with little or no human contact. One source told ABC News that Paddock was exhibiting many antisocial traits that are typical of past mass shooters.
