Family members say Argueta is a mom of a toddler and was out to celebrate her birthday with her family when she was hit.  The family also said she’s now on life support and if she ever wakes up she may have brain damage.

Neighbors say cars rush through the intersection all the time.

“A lot of speed, that’s probably the third accident today on the street right here,” Tashana Prosser said.

Argueta was outside a crosswalk at the time but the nurse says it doesn’t justify the driver taking off.
