A gunman opened fire late Sunday during a country music concert on the Las Vegas Strip, killing at least 50 and leaving more than 400 wounded. Clark County Sheriff Joseph Lombardo says that the shooter, Stephen Paddock, was a 64 year old white man that lived in the local area and was killed by police during the incident.
Fox News reports one on-duty officer in critical condition and another was wounded in the shooting. Two off-duty police officers attending the concert were killed. The gunman, who fired down on the concert from a room on the 32nd floor of the Mandalay Bay Hotel and Casino, was killed by police. Clark County Sheriff Joseph Lombardo says the suspect is a Vegas resident and they believe this was a  "lone wolf" attack but said they were looking for a roommate of the dead suspect as a person of interest. Marilou Danley was described as 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. She is currently being questioned by police.

Police began getting calls about an active shooting just after 10pm.

Jason Aldean was performing at the Route 91 Harvest Festival when the gunfire erupted.
