Timeline: Disappearance and Search for missing 5-year-old girl Dulce Maria Alavez
The girl and her 3-year-old brother were playing while their mother sat in her car with an 8-year-old relative, but her son soon ran to the car crying and pointed to the area where he last saw his sister.
On Saturday, members of the community gathered in the 1700 block of S. Burlington Road for a candlelight vigil.
Multiple searches for the child have not turned up any leads.
There is a $52,000 dollar reward being offered in the case.
