A group holds a vigil in downtown Las Vegas after Sunday's mass shooting.

A gunman holed up on the 32nd floor of a Las Vegas hotel fired indiscriminately down upon a crowd of thousands gathered for an outdoor country music festival.

The numbers are staggering with at least 59 dead and nearly 530 injured in what has become the worst mass shooting in modern American history.

The gunman, 64-year old Stephen Paddock, was a so-called lone wolf. He lived about 90 minutes away from Las Vegas in Mesquite, Nevada, in a retirement community.

According to reports, he liked traveling to Vegas to play high-stakes video poker. He apparently didn’t have anything significant as far as a criminal record.

Paddock later killed himself as SWAT teams moved in on his location overnight.

By some estimates, Paddock fired for at least 10 minutes after breaking out windows at the Manadalay Bay Hotel and Casino.

Among the dead and injured were several Minnesotans, including a Concordia Academy graduate who is in critical condition. St. Paul Police Chief Todd Axtel was in town with friends at the time.

Minnesota radio DJ Katie Toupal was at the concert and described her experience to Fox 9. Several other Minnesotans spoke out after they returned home on Monday.

About 22,000 music fans attended the 3-day Route 91 Harvest Festival.
