Reason behind Maine anthrax hoaxes remains a mystery

Federal authorities have found no motive for why two elementary schools in York, Maine, recently received letters containing a white powder.

The two schools were among several in New England that received the threatening mail. Local officials said that they have no information that the letters were intended for any specific school or person, according to

"I don't think there's any rhyme or reason," York Police Chief Doug Bracy said, reports.

"I don't know what's behind it, or any specific reason it was York," York School District Superintendent Henry Scipione said, reports.

Four Maine schools, including York's Village and Coastal Ridge Elementary, received white powder letters. They were all postmarked from Dallas, Texas, and sent within the past two weeks.

FBI Special Agent Greg Comcowich said that schools in New Hampshire, Massachusetts and Rhode Island were also targeted. In all cases, the white powder turned out to be a hoax.

"Preliminary tests indicated no threat to public safety," Comcowich said, reports.

Comcowich also said that threatening mailings have become an ongoing, nationwide phenomenon since the 2001 anthrax attacks.

"It happens all too frequently," Comcowich said, according to "We pursue it vigorously because of the nature of the crime. We treat all as if they're real. It takes up a substantial amount of investigative resources."
