Investigators looking into the Las Vegas massacre say they have a person of interest — but it's not clear who.
Authorities released an initial report on their investigation Friday. It says the shooter, Stephen Paddock, did a lot of research before the massacre. He looked up police and SWAT tactics, as well as other potential targets. Authorities said the shooter also had child pornography. His brother was arrested in connection to a child porn investigation that started before the shooting.
Clark County Sheriff Joe Lombardo said Friday the FBI has an "ongoing case against an individual of federal interest." He didn't get any more specific than that. CNN reports prosecutors could bring charges in the next 60 days, but it's not clear who they would be against.
The report doesn't include a clear motive, but Lombardo said the shooter had lost a lot of his wealth in the days leading up to the shooting.
During a news conference Friday, Lombardo said Paddock's financial situation "could be" a motive.
Investigators say the shooter acted on his own, and there was no connection to international terrorism or radicalization involved.
