ROCKVILLE, Md. (AP) -- Investigators searching for a sniper terrorizing the Washington suburbs found a Tarot card with the words, "Dear policeman, I am God," near a bullet casing outside the school where a 13-year-old boy was critically wounded, a source familiar with the investigation confirmed Wednesday.
Police were also searching a wooded area behind a school in Prince George's County after reports Wednesday of a suspicious person seen in the area.
Montgomery County Police Chief Charles Moose, who has been leading the investigation, wouldn't comment about the card and said he was concerned that unapproved information was being leaked.
"I need to make sure I don't do anything to hinder our ability to bring this person or these people into custody," Moose said Wednesday.
The taunting message left on a Tarot card known as the Death card, first reported Tuesday night on WUSA-TV and then by The Washington Post, was confirmed by a source Wednesday to The Associated Press.
The shell casing was being checked against the National Ballistics Identification Network, a database of crime-scene firearms evidence maintained by the federal Bureau of Alcohol, Tobacco and Firearms.
The motive for the seemingly random crimes still eluded police Wednesday, one week after the first of six slayings. Nearly 200 investigators were working their way through 1,600 leads culled from 8,000 tips.
"We need just a shred of evidence," Prince George's County Police Chief Gerald Wilson said.
Police sources told the newspaper that the Tarot card was found next to the spent shell casing in a wooded area about 150 yards from the school entrance in an area of matted grass, suggesting the gunman had lain in wait.
