From a sunrise event to an after-dark reading of victims' names, Las Vegas plans to mark the anniversary of the deadliest mass shooting in modern U.S. history with memorials to the 58 people killed two years ago.

Joe Robbins, whose 20-year-old son, Quinton Robbins of suburban Henderson, died in the Oct. 1, 2017, attack, joined Nevada Gov. Steve Sisolak, Clark County Sheriff Joe Lombardo and others for the Tuesday daybreak ceremony at the Clark County Community Center. 

During the morning ceremony, Sisolak said, "As painful as it may be, especially on a day like today, our capacity to remember, to feel what we felt all over again, is what binds us together as a community - as a family and it makes us strong."

Governor Sisolak was chairman of the Clark County Commission when the shooting happened. He started a GoFundMe page that raised more than $11 million for victims. 

The Vegas Strong Resiliency Center plans to promote wellness programs during the day, and the maker of wooden memorial crosses plans to offer them to family members.

Las Vegas Mayor Carolyn Goodman is scheduled to mark the time of the shooting at 10:05 p.m. by reciting the names of the slain at a downtown Community Healing Garden.

Flags will be flown at half-staff at the state capitol and all state public buildings and grounds, in remembrance of the lives lost. 

Authorities say Stephen Paddock shot and killed 58 people and injured nearly 700 others in the Las Vegas rampage. Authorities finally found Paddock's body inside his Mandalay Bay Hotel room.

Police believe Paddock took his own life and that no one else was involved with the shooting.

Democratic Senators Catherine Cortez Masto and Jacky Rosen both released statements on the anniversary. 

Sen. Cortez Masto says: 

"Two years ago, our state of Nevada was transformed. 58 people were enjoying an evening of music with family and friends when their lives were taken from them and hundreds more were injured in what would be the deadliest mass shooting in modern American history.

When I think about the Route 91 Massacre, my heart aches for the loved ones of those who didn’t come home that night and for those still recovering from the physical, mental and emotional wounds they suffered that night.

I also think about those who ran into the crowd—towards danger—to help others. The everyday heroes, first responders, and medical professionals who made a difference.

And I’ll never forget the sea of people who lined up to donate blood or the candle light vigils that provided our communities a place to reflect.

I’m so proud of my hometown of Las Vegas and how we came together—and are still coming together—for the survivors and the families of the victims. We came together as a city—and as a state—and displayed incredible strength and unity in the face of tragedy.

I will always remember the Route 91 festival victims and their loved ones. And though the pain will never fully fade away, I’m thankful to see our community coming together to bring healing with each new day.

On this solemn anniversary, let’s honor the 1October victims and their loved ones and those who risked their own safety to help others. 

Today, and every day, we’re Vegas Strong."

Sen. Rosen released this statement: 

“On October 1st, 2017, the city of Las Vegas experienced tragedy on an unprecedented scale, tragedy that has left our community deeply scarred and our city forever changed,” said Senator Rosen. “Today, we honor the memory of the fifty-eight victims who lost their lives, and the hundreds more who were injured and are still fighting to recover. We must also remember those who made the selfless choice to run toward the gunfire to help. Know that the bright lights of Las Vegas will continue to shine through the darkness of that day. We are resilient, and we will always be Vegas strong.”
