Apart from the twinkling lights of hotels and casinos , a small healing park was opened in the north of Las Vegas , as part of citizen efforts to heal the wounds left in the city by the fatal shooting last Sunday.

After escaping Hurricane Harvey in Houston, Royce Christensen worked at the Las Vegas music festival.

When she was under fire, dodging bullets at the Route 91 Harvest festival on Sunday, Megan Greene felt an odd sense of purpose. "If you're still breathing, you're fine," she told a panicky woman trying to escape with her mother, who uses a wheelchair.

Jill Roberts heard the screaming and crying in the Sunrise Hospital and Medical Center emergency room Sunday night as the families and friends of those killed in the Route 91 Harvest music festival shooting found out their loved ones didn’t survive the attack.

Christie White, 46, smiles thinking of her last peaceful memory. It was a girls’ weekend. It was Sunday night. Christie and Dani and Beth were hanging out in the perfect late-summer weather under glimmering Las Vegas lights with some cocktails, and their favorite country bands.

The volunteer psychologists and counselors have been pouring into this grieving city, so fast that a state official says the supply far exceeds the demand for crisis counseling.

We often think of first responders mainly as police, fire and emergency-medical professionals. In Las Vegas on Monday, NPR's Eric Westervelt found a small volunteer army of mental-health professionals, trauma counselors, psychiatrists and social workers who quickly fanned out to help some of the thousands who had witnessed the massacre up close.

Experts from across the valley have taken a hard look at both the city and state’s mental health care situation, and most agreed that, in order to fix things, it will take time, new professionals and lots of money. “Mental health funding draws from several fronts, and there is room for growth in all those fronts,” said Jim Jobin, president of the National Alliance on Mental Illness. “Nevada has the fewest clinicians of any state — that’s providers who can sit with you and know what to do. In Nevada, only one in three adults that has mental illness will be able to get help. Only one in two children who have severe mental illness can get any help. There’s not enough of us to go around.”
