UPDATE JULY 10: The Clark County coroner has identified the woman in a deadly crash on Tuesday as 56-year-old Rose Mary Modica.
Loved ones want Rose Mary Modica to be remembered as a loving, caring grandmother who always put her grandkids first.
She was with those children Tuesday to celebrate her birthday when her car barreled through a construction zone.
David Carnell saw her car in his rear view mirror, speeding and swerving as if the driver had no control of the vehicle.
"It honked twice just like real quick sharp honks kinda like get out of the way. The car actually swerved around my truck, swerved around the truck that was to the left of me."
Police say a 2007 Toyota Camry was observed traveling at a high rate of speed on West Washington Avenue. For an unknown reason, the car then ran into the construction cones and barricades and a construction truck
After hitting the construction truck, the left front wheel assembly separated from the Camry and hit a pedestrian on a sidewalk. The Camry then struck a Bobcat front loader.
Police have confirmed that there were 4 children in the car with the woman at the time of the crash. All 4 children -- ages 10, 9, 4, and 2 -- were seriously injured.
A 31-year-old man at the scene was also seriously injured.
Carnell helped pull the children from the wreckage.
"Obviously the children loved her very much. Like I said, the oldest, I think his name is Herman, I asked for his name trying to calm him down. He's like I want my grandmother. I want my grandmother... I feel very much for the family. I don't believe it was her fault. I believe something was wrong."
Multiple vehicles were hit with flying rocks and debris. Modica, who was not wearing a seatbelt, was ejected.
Modica and the children were all transported to UMC Trauma and Modica did not survive.
The children remain in the hospital but are expected to survive.
The cause of the crash is unknown at this time.
Relatives told us Modica had a knee surgery that could've been an issue. Her car, a 2007 Camry, was one of the models recalled in 2009 for acceleration issues connected to stuck gas pedals.
It's still not known if this car was taken in for repairs.
This is the 58th traffic related death so far this year in Las Vegas.
