An Arlington-based legal investigative unit filed a lawsuit Wednesday seeking to force D.C. police to turn over information gathered in last year’s fatal shooting of Democratic National Committee staffer Seth Rich.

The Profiling Project, headed by lobbyist and lawyer Jack Burkman, along with law students at George Washington University, filed the suit in D.C. Superior Court in hopes it can gain access to surveillance video from a camera at the Flagler Market, near where Rich was killed; the D.C. Medical Examiner’s report on the death; and the forensic ballistic report.

Burkman is asking that D.C. police release the information within 10 days. Named as defendants in the lawsuit are Mayor Muriel E. Bowser (D) and D.C. Attorney General Karl A. Racine.

Rich, 27, was shot July 10 in the District’s Bloomingdale neighborhood. D.C. police have repeatedly said that they think Rich was killed in a random robbery attempt, but several conspiracy theories have emerged about his death. No arrests have been made.

“The family remains completely confident in the Metropolitan Police Department’s handling of the case,” Brad Bauman, a spokesman for the Rich family, said in a statement.
