While the investigation continues into the March 11, 2016 murder of Johan De Leede in the 6000 block of River Drive in the Mason Neck area, Fairfax County Police said Major Crimes Division detectives are still asking any individuals with additional information about the case to come forward.

This comes after officers established an increased neighborhood patrol presence that included the Police Department’s helicopter and other assets, canvassed the neighborhood in April, and conducted a motorist checkpoint for drivers entering the Hallowing Point community.

“Detectives have collected a substantial amount of information through these efforts,” a May 2 release said. But they’re still hopeful to collect something new from the public. “Remember, the information you have, regardless of how trivial you feel it may be, could be the critical link in solving this case.”
