In scenes that have become all too familiar in and around Washington, police have sealed off the site of another shooting, although they say it is too early to know if it is connected with the killer marksman. A man was shot and wounded with a single bullet outside a steak house in Virginia. If a link is confirmed, it is the sniper's first attack in nearly a week, and the first time there has been an attack during a weekend. It comes at a time when the police are following up on a new lead. A white box van from a hire car company is being examined after a shell casing was found inside. Police say it is too early to tell if it is connected with the crimes.
