I live in the Washington DC area. In October 2002 we had the Beltway-DC snipers - Lee Boyd Mlavo and John Allen Muhammad. These two men killed 10 people and injured 4. The killings happend less than 10 miles from where I lived. Some people were killed in Virginia
People were afraid to go out in the public. Some of the killings happened at gas stations and a school. I remember people telling me that when they went to a gas station to pump gas - they either sat in their cars or they move around to keep from being a target. Parents kept their kids home from school.
Malvo and Muhammad murdered 16 people and injured 4 in 8 states.
It was a relief when those two idiots were captured at a Maryland rest stop.
