Staff at the Shapiro Admissions Center reported receiving a suspicious white envelope that contained what appeared to be marijuana seeds on March 4, according to a campus police report.Director of Admissions Deena Whitfield said the envelope was addressed to "A.B." and had no return address.

"We have no idea who it came from," Whitfield said.

Director of Public Safety Edward Callahan picked up the envelope and contacted the U.S. Postal authorities.

"It's their prerogative to look into this concern," Callahan said.

Callahan said the admissions office occasionally receives mail that violates state, federal, or municipal laws, and that he has to report such infractions to outside authorities.

"That's the obligation that we have," Callahan said.

Callahan said he has not received further information about the envelope or the nature of its contents.
