From the first Morning Jolt of the week:

Awakening to the News of the Most Deadly Shooting in U.S. History

An awful way to start the week:

At least 50 people are dead and more than 200 wounded after a gunman opened fire on a music festival on the Las Vegas Strip in the most deadly shooting in U.S. history.

Police said the suspect, identified as 64-year-old local resident Stephen Paddock, was located on the 32nd floor of the Mandalay Bay Hotel and Casino when he took aim at the nearby Route 91 Harvest Festival.

Local television news reports showed crowds of people in Las Vegas ducking for cover as the sound of rapid gunshots rang out, while dozens of patrol vehicles descended on the Strip.

Joseph Lombardo of the Las Vegas Metropolitan Police Department said the suspect was shot dead by officers and that authorities were confident there was no longer a threat.

He said police found numerous firearms in the room he occupied and that officers were also at his residence.

The death toll may surpass the current total; the Pulse nightclub shooting in Orlando, committed by jihadist Omar Mateen, killed 49 people and injured 58 more. The death toll from Virginia Tech was 32; Sandy Hook, 27.

Notice this detail: “The suspect was known to police in Mesquite and had a criminal history, the sources said. Lombardo said authorities believe they had found a traveling companion of the deceased gunman they were seeking, who Lombardo identified as Marilou Danley, 62. Law enforcement sources tell Milton that Danley was Paddock’s wife.”

One can’t help but wonder if she is related to this particular unnerving detail from a survivor’s account:

A woman who was at the concert told a local news station that a “lady pushed her way forward in the concert venue. And she started messing with another lady and told us that we are all going to die tonight. … It was about 45 minutes [before] the shots were actually fired. But then she was escorted out by security.” But police have not confirmed if they believe that was related to the shooting.
