LAS VEGAS - (AP) - Police say the man who killed at least 50 people and wounded more than 400 at a Las Vegas concert was a retiree with no criminal history in the Nevada county where he lived.

The brother of 64-year-old Stephen Paddock said he's "completely dumbfounded" by the shooting at a country music concert Sunday night, which is the deadliest in modern U.S. history.

CNN reports Paddock was a retired accountant who enjoyed playing $100-a-hand poker. CNN also reported Paddock's father was a bank robber. Stephen Paddock held a pilot's license but did not have medical certification to fly.
