LAS VEGAS — The motive behind the deadliest mass shooting in modern U.S. history remained a mystery Monday as police sought to learn more about the apparent “lone wolf” gunman who opened fire on thousands of concertgoers from the 32nd floor of a Las Vegas hotel.
At least 58 people were killed and hundreds more were injured in the shooting, which happened during a performance by country music star Jason Aldean Sunday night at the Route 91 Harvest Festival. The gunman hammered out a window at the Mandalay Bay Hotel and Casino and began firing with a cache of weapons . Authorities who stormed the suspect’s room found that he had killed himself.

Heather Melton told WZTV in Nashville that her husband “saved my life and lost his.” She says her husband was the most kind-hearted, loving man she ever met.
Others slain include commercial fisherman Adrian Murfitt, 35, of Anchorage, Alaska; Lisa Romero, a high school secretary from Gallup, New Mexico; Rachael Parker, a records technician with the Manhattan Beach Police Department; and mechanics’ apprentice Jordan McIldoon, 23, of Maple Ridge, British Columbia.
Paddock’s brother, Eric Paddock, who lives in Florida, says his multimillionaire brother was a big spender at casinos and often received free meals and rooms there.
Eric Paddock also described his brother as different than other people: “He was a guy who had money. He went on cruises…
