LAS VEGAS (AP) – Investigators are reconstructing the life and recent activities of the Las Vegas shooter who killed 59 people – but still have not concluded what motivated retired accountant and high stakes gambler Stephen Paddock to commit the worst mass killing in recent U.S. history.

Paddock’s girlfriend, who was in the Philippines during Sunday’s bloodbath, was met by FBI agents at Los Angeles airport and was expected to be questioned on Wednesday.

And President Donald Trump was heading to Las Vegas to with law enforcement officers and the survivors of the country music concert shooting outside the Mandalay Bay hotel casino.
