A judge in Brooklyn on Wednesday heard testimony in a case that pits the mother of a man who died in the 2001 terrorist attacks on the World Trade Center against her former husband, who wants half of their son’s $2.9 million award from the federal September 11th Victim Compensation Fund.

Brooklyn Surrogate Margarita Lopez Torres held a daylong hearing that included testimony from the mother, Elsie Goss-Caldwell; the father, Leon Caldwell; their eldest son, Leon Jr.; and family friends.
