On Sunday, Palm Mortuary downtown hosted their first World Day of Remembrance event in Las Vegas.
One in four adults has lost someone they love in a traffic crash. World of Remembrance for Road Crash Victims brought the victims' families and community together to remember loved ones and help one another.
Each participant were given an ornament with their person's name and life dates to add to a tree during the ceremony.
One of the moms in attendance, Crystal Hill, lost her son New Years Day 2013.
"My son, 18-year-old Jesse Hill was walking on the sidewalk with his girlfriend and they were hit by an impaired driver," Hill said.
His girlfriend Anne-Marie Ricci was 16 at the time.
"It's tough -- he pushed me out of the way so for me, I'm here because of him," Ricci said.
She now lives with a traumatic brain injury.
"Trying to overcome that has been very difficult," Ricci said.
And for Crystal Hill, for this single mom, there is nothing worse than a mom losing a child, but what makes it so much harder is that it could have been prevented.
