It has been revealed that two dozen firearms have gone missing from an evidence locker at the Washington, D.C. Metropolitan Police Department, with some being used in other crimes.

According to an internal memo from the D.C. Department of Forensic Sciences, officers first confiscated the weapons between 2005 and 2012 – but some were later confiscated again after being used in additional violent crimes, while others were returned and mysteriously re-logged into the police database.

The revelations give serious credence to allegations that officers or federal employees who have access to the locker have been using the firearms for their own nefarious purposes.
