Jose Luis “Joe” Cacheux-Ojeda, 59, looks at the memorial tree with loved ones during the memorial service for the victims of the Sept. 16 National Championship Air Races crash in Reno, Nev., on Sunday, Sept. 25, 2011. Ojeda lost his partner of 35 years Sharon Olthea Stewart of Reno, Nev., in the crash.

RENO, Nev. — More than 400 people gathered at a park in Reno, Nev., to pay their respects to the victims of last week's deadly crash during an air race and to dedicate an oak tree to their memory.

Reno Mayor Bob Cashell said Sunday night that it was important not only to support the families of the 11 killed and 70 injured but also for the community to begin healing.

Gov. Brian Sandoval says the tree will help preserve the memory of one of the most important incidents "in the collective life of a community."

He says Nevadans should be proud of the shared humanity they demonstrated in the face of the emergency, from firefighters and doctors to those who stood in line to give blood or "simply stood and prayed."
