THE DISTRICT

Missing jail inmate: D.C. Corrections Department officials are investigating the disappearance of a prisoner from the D.C. jail.

Inmate Michael Gillis, 49, who is awaiting trial on a misdemeanor burglary charge, arrived at the jail Friday night. He was discovered missing early Saturday. A spokesman said the department was investigating whether Gillis was erroneously released or whether he got out because of a security lapse. The Corrections Department's warrant squad has been assigned to look for him, a spokesman said.

VIRGINIA

Officer's badge taken: Thieves who made off with a Fairfax County police officer's personal car last week also may have taken a police jacket and the officer's badge from the trunk, raising concerns that someone could pretend to be an officer, police said yesterday.

Prince William County police said that the officer's car was stolen from Glendale Road in Dale City on March 5 and that it was later found in the District. Police said the official jacket and badge were missing from the trunk.

Police warned Northern Virginia residents that someone might try to impersonate an officer, adding that police also carry photo identification cards issued by their departments.

MARYLAND

Two fatally shot: Prince George's County police are investigating an apparent murder-suicide that occurred yesterday in the Oxon Hill area, authorities said.

A 17-year-old found his mother and stepfather in a bedroom of the family home in the 1100 block of Lindsay Road and called police about 4:45 p.m., said Cpl. Tammy Sparkman, a police spokeswoman. Police believe the man shot the woman with a handgun before turning the weapon on himself, Sparkman said. Police did not release their identities last night, but Sparkman said the woman was 33 and the man was in his mid-thirties.
