Las Vegas mourns victims of mass shooting with vigils and tributes

Tributes include candles, balloons, flowers and photographs.

— -- Under the bright Las Vegas lights, mourners have been coming together at vigils for victims of the mass shooting Sunday night that left 58 people dead.

On the Strip, the names of those who died were written in chalk on the pavement.

The 58 victims include Sonny Melton, a nurse from Tennessee, who died shielding his wife, who survived; Jennifer Parks, who had just entered her third year of teaching kindergarten in Palmdale, California; Rocio Rocha Guillen, who was a mother of four, including a 1-month-old baby boy; and Charleston Hartfield, a Nevada Army National Guard Sgt. 1st Class and a Las Vegas police officer, who was off-duty and attending the concert when he was shot and killed.

The attack was the worst mass shooting in modern U.S. history.

Police continue investigating the motive of the suspected gunman, who they said killed himself.
