Clark County Sheriff: More than 50 Dead, 400 Wounded in Las Vegas Shooting

Clark County Sheriff Joseph Lombardo said more than 50 are dead and 400 wounded after a gunman opened fire at a country music concert on the Las Vegas Strip. Country music star Jason Aldean was performing at the Route 91 Harvest Festival when the gunfire erupted.

The gunman, who has been identified as Stephen Paddock (corrected from Steven), fired down on the concert from a room on the 32nd floor of the Mandalay Bay Hotel and Casino. Paddock, 64, was from Mesquite, Nevada and was known to local police.

UPDATE: Sheriff Lombardo said authorities believe Paddock killed himself prior to their entry into his hotel room.

Sheriff Lombardo said authorities believe this was a “lone wolf” attack, but they were looking for a person of interest: Marilou Danley, an Asian female, about 4’11 and 111 pounds. Authorities told the public to keep an eye out for a Hyundai with a Nevada plate: 114B40 and a Chrysler with a Nevada plate 19D401.

UPDATE: Detectives later made contact with her and now “do not believe she is involved with the shooting on the strip.”

Authorities first received calls about an active shooting at about 10:08 p.m. An on-duty officer was in critical condition and another was wounded in the shooting, while two off-duty police officers attending the concert were killed.

If the death toll holds, it will be the most deadly mass shooting in U.S. history.
