Two others were severely injured. The murders took place at 7700 16th Street NW, a Washington, D.C. house purchased for a group of Hanafi Muslims to use as the "Hanafi American Mussulman's Rifle and Pistol Club". The property was purchased and donated by then Milwaukee Bucks basketball player Kareem Abdul-Jabbar.The target of the attack was Hamaas Abdul Khaalis, the son-in-law of Reginald Hawkins. Khaalis had written and sent fifty letters calling Nation of Islam leader Elijah Muhammad "guilty of 'fooling and deceiving people – robbing them of their money, and besides that dooming them to Hell.'" The letters were mailed to ministers of all fifty mosques of the Nation of Islam, a sect that Khaalis had infiltrated and in which he had been a leader in the 1950s. The letters were also critical of Wallace D. Fard and urged the ministers to leave the sect.

Shepherd Park is a neighborhood in the northwest quadrant of Washington, D.C. In the years following World War II, restrictive covenants which had prevented Jews and African Americans from purchasing homes in the neighborhood were no longer enforced, and the neighborhood became largely Jewish and African American. Over the past 40 years, the Jewish population of the neighborhood has declined (though it is now increasing again) but the neighborhood has continued to support a thriving upper and middle class African American community. The Shepherd Park Citizens Association and Neighbors Inc. led efforts to stem white flight from the neighborhood in the 1960s and 1970s, and it has remained a continuously integrated neighborhood, with very active and inclusive civic groups. Shepherd Park and the rest of Ward 4 were represented in the Council of the District of Columbia by Muriel Bowser, until her election as Mayor of the District of Columbia in the fall of 2014. It is home to a number of prominent people, including former NAACP President Benjamin Jealous. A number of judges, professors, newspaper reporters, and doctors also live in the community.

Colonial Village is an area in northwest Washington, D.C., built in 1931 with 80 residences. The homes are reproductions of colonial buildings, such as the Moore House, where General Charles Cornwallis surrendered at Yorktown. The community was mostly Protestant, in contrast to the nearby 220-house North Portal Estates, which was a mostly Jewish neighborhood. When the community was first constructed in 1931, the neighborhood was exclusively populated by white Protestants as black and Jewish people were prohibited from living in Colonial Village. The land on which Colonial Village lies on, was once the 145 acre plantation of slaveowner Phillip Fenwick. After the mid-20th century, both Colonial Village and North Portal Estates became part of Shepherd Park.

Rock Creek Gardens is an affluent residential neighborhood in Northwest, Washington, D.C. It is bounded by West Beach Drive to the east and northeast, Parkside Drive to the south and southwest, and Rock Creek Park to the northeast.

North Portal Estates is an affluent residential neighborhood in Washington, D.C. that forms the northernmost corner of the District of Columbia. North Portal Estates is bounded by North Portal Drive to the south, East Beach Drive to the west and northwest, and Rock Creek Park to the northeast. It is not set on any major thoroughfare in the city, although North Portal Drive is accessible via a rotary intersection on 16th Street NW. Because of its isolation via the park and lack of major streets, the neighborhood is extraordinarily suburban in character, full of winding streets, detached houses on large lots, and open space. North Portal Estates and the rest of Ward 4 are represented in the Council of the District of Columbia by Janeese Lewis George. The community was mostly Jewish, in contrast to the nearby Colonial Village, which was a mostly Protestant neighborhood. The community was constructed by wealthy Jewish families in the 1950s and 1960s, following the 1948 Supreme Court decision striking down racially restrictive covenants. The homes in North Portal Estates are larger and more recent than the older homes in Shepherd Park. Racial covenants were prohibited by law by the 1968 Fair Housing Act. African-Americans began moving into North Portal Estates in the late 1960s and early 1970s, comprising two-thirds of the population by the 1980s as the older Jewish population began to move away or die. By the early 1980s, North Portal Estates had become a premier neighborhood for upper-middle-class African-American professionals in Washington, D.C., including doctors, lawyers, business people, clergy, and politicians. While mostly black, the neighborhood is multiracial as some white Jewish families have remained in the neighborhood. By the 2010s, the neighborhood was still predominantly upscale, but had become home to a more socioeconomically and racially mixed population.
