Tucker, 30, is one of three black transgender women killed this week in the United States and one of at least five transgender women of color killed in Philadelphia since 2013. There has been a documented uptick in homicides reported against transgender women over the last five years, and 2018 could be the "deadliest" on record for the group, according to Mara Keisling, executive director of the National Center for Transgender Equality, which has counted 21 such homicides this year.
