Brother says Las Vegas shooter was multi-millionaire real estate investor

LAS VEGAS (AP) - A brother of Las Vegas shooter Stephen Craig Paddock says he was a multimillionaire who made much of his money investing in real estate.

Eric Paddock told reporters Monday in Orlando that his brother was also an accountant for many years.

He was not aware of his brother having any recent financial difficulties.

Stephen Craig Paddock recently sent a walker by mail to his 90-year-old mother. The brother says the shooter collected coins when he was a child.

Police have said the suspect killed at least 58 people in the worst mass shooting in recent U.S. history.

Paddock is believed to have checked in as a hotel guest before the attack, which left at least 58 people dead and more than 515 injured.

"We've located numerous firearms within the room that he occupied," Lombardo told the media. "We have no idea what his belief system was. Right now, we believe he was the sole aggressor and the scene is static."

Responding officers blew the door open and then entered the room. Once inside, police said they found him dead inside the room. 

Federal law enforcement sources told Fox News that Paddock "was known to local authorities," in Las Vegas. But police in Mesquite, where Paddock lived, said he never had any run-ins with officers, the Desert Valley Times reported.
