LAS VEGAS — Authorities are planning to put up billboards in Las Vegas to seek more tips as they investigate the deadliest shooting rampage in modern U.S. history.
Undersheriff Kevin McMahill also revealed at a news conference Friday afternoon that police are confident there was not another shooter in Stephen Paddock’s room.
Paddock fired indiscriminately Sunday from his upper-level room at the Mandalay Bay hotel casino at people attending a country music festival below, killing dozens and injuring nearly 500 people. The 64-year-old Paddock killed himself as authorities closed in.
McMahill also said that authorities don’t have any information that anyone else used Paddock’s room key.
He says authorities are interested in Paddock’s medical history and are looking into that.
