Much property crime in the Washington area appears to stem from a desire for quick cash. But some seems prompted primarily by ill will, with no hope of financial reward, such as the vandalism that damaged more than 20 cars over the weekend in Montgomery County.

In a separate vandalism incident in another part of the Washington region, a toilet was removed from the floor of a restroom at a laundromat in Fredericksburg, Va., early Friday, flooding the premises, police there said.

In Montgomery, police said at least 21 people had car windows broken, tires slashed or both in the Olney area between 11 p.m. Saturday and 5 a.m. Sunday.

Police said some of the 21 victims found damage to more than one of their vehicles.

The incidents occurred in four neighborhoods, the police said. One neighborhood was near Georgia Avenue and King William Drive, and a second was near Cashell and Bowie Mill roads. The other two areas were near Old Baltimore and Gold Mine roads and the section of Olney Sandy Spring Road between Sherwood High School and Brooke Road.

Some of the intersections are a mile or more apart.

County police said they were trying to determine whether the vandalism was linked to a burglary about 2:20 a.m. in the 3800 block of Terrawood Court. Property was taken from a parked car and a garage.
