NORWALK - Two southwestern Connecticut families are mourning the deaths of their daughters after the women were killed in a car accident Saturday.

Police say 23-year-old Whitney Williams' and 26-year-old Tiffany Russell's car crashed into a guard rail on I-91 near exit 14 in Wallingford. Family members say the two women were out celebrating Russell's birthday and the new year.

Williams' sisters and mother say she was a good, kind and loving person who helped her family and anyone else in need. Russell's grandmother says her death is unbearable and Russell's mother says her daughter often held the family together.

Both women leave behind infants.
