Paddock's girlfriend denies attack-Las Vegas shooting

Marilou Danley's comments came hours before police suggested Stephen Paddock had been living "a secret life".

They said he may have been planning to escape instead of shooting himself dead, but did not give further details.

It is not yet known why he opened fire on an open air concert, committing the worst shooting in modern US history.

Clark County Sheriff Joseph Lombardo said in a press conference on Wednesday:

Police had found more explosives in Paddock's car at the hotel, along with about 1,600 rounds of ammunition

Paddock had been gambling just hours before he began shooting

He had booked into the Ogden Hotel overlooking a different open air festival in Las Vegas a week earlier

But he said Paddock's motivations and whether there were any possible accomplices remained a mystery. The FBI has said so far no link to terrorism had been found.

"We don't understand it yet," Sheriff Lombardo told reporters.

Ms Danley, who spoke to the FBI on Wednesday after travelling back voluntarily from a holiday in the Philippines, expressed shock at the "horrible unspeakable acts of violence" Paddock had committed.

Paddock "never said anything to me or took any action" which she understood as a warning of what was to come, she said in a statement read by her lawyer.

Ms Danley added: "I loved him and hoped for a quiet future together
