Threats in the form of a suspicious powder have been received by several of the drivers accused of using a west-metro interstate for a racetrack recently in exotic sports cars at more than 100 miles per hour, a defense attorney said Monday.
"Several of the individuals have received anonymous packets in the mail containing white powder," said Marsh Halberg, who is representing at least four of the 12 defendants charged with reckless driving in connection with the high-speed cruise on April 23 along westbound Interstate 394 that continued after the route changes to Hwy. 12.
"There is a genuine concern for the safety of the individuals at this time," Halberg said. He added that there have been no ill-effects from the contents of the packets.
Halberg said the packets have been turned over to the FBI, which "has been very responsive" as it investigates the items.
An FBI spokesman declined to confirm or deny that it's looking into the matter, a standard response unless the agency is seeking public assistance in an investigation.
There's been no determination yet on the makeup of the white powder, Halberg said. "I don't want to speculate on why someone would send the envelopes," he added.
Soon after the terror attacks on Sept. 11, 2001, letters containing anthrax spores were mailed to several news media offices and two U.S. senators, killing five people and infecting many others.
Since then, federal agencies have investigated and charged numerous people nationwide with biological-weapon hoaxes and threats. Many of those hoaxes involve what was presented as anthrax, a white, powdery substance.
