Las Vegas, NV (KTNV) -- Minutes after the horrific crash at the candlelight vigil for Helen Liu, a child described as a wonderful daughter, happy, fun-loving and a good student, her parents fought back both tears and anger.
Helen's mother, Lianfan Liu said, "My daughter, Helen, is really an angel, because she sacrificed herself to make the let the government or some department to make the big decision."
A decision to listen to their pleas to save lives.
Pleas the Liu's and other parents along Blue Diamond have been making for months.
LaRae Dicamillo said, "We are way beyond the point of a crosswalk, because this street is so dark, when you turn these lights off? You cannot see."
Mike Motorozesku said, "This is the most dangerous. When I moved over here on Blue Diamond and Durango, in one month there were four deaths."
Spurred to action by these tragedies, Helen Liu's classmates and their parents are signing a petition, demanding a traffic device at Blue Diamond and Cimarron.
They said they're tired of being stonewalled by what they say is an excuse, that Blue Diamond wasn't intended to be a residential thoroughfare.
Now that neighborhoods surround it they say, it is.
LaRae Dicamillo said, "This county or city or whoever you are, they need to wake up and they need to start taking better care of our kids."
Helen Liu's father said he's willing to do whatever it takes to make sure no parent endures his pain, "We've got to do something to let our voice heard, to prevent similar tragedy happening in the future."
