Marco McMillian's family is publicly calling for an investigation by the FBI into his death saying his murder investigation was disrespectful to his family, a violation of his civil rights and left many unanswered questions.
The McMillian family has hired Parks and Crump as their attorneys in the matter. They are the same attorneys representing Trevon Martin's family. Martin was the Florida teenager whose 2012 death at the hands of a neighborhood watch volunteer sparked protests and outrage.

The family alleges that Marco's murder may have been because of his questions in the community and because of political overtones.
The Clarksdale, Miss., mayoral candidate's body was found Feb. 27.
The case drew national attention after his campaign said he was the first viable, openly gay candidate for office in Mississippi.
Mr. McMillian's sexuality wasn't a campaign issue, but because the 33-year-old was gay and black, some speculated his death might have been a hate crime.
The suspect in the case also is black.
