Frederick Ezekiel Booker, 29, was shot and killed in Washington, D.C., on the evening of Sunday, May 5, 2013. He was found inside a vehicle in the 4100 block of 20th Street NE at about 6:41 p.m., transported to a local hospital, and pronounced dead. The Metropolitan Police Department opened a homicide investigation and sought the public’s help.

Known to family and friends as Ziggy and Zekey, Booker was a father to two young daughters, ages six and eight at the time. More than 100 people attended a May 10 candlelight vigil at the Michigan Park Recreation Center. His mother, Charlene Booker, had earlier lost another son, Charles Booker, to gun violence in 2002.
