A man has acknowledged sending suspicious letters containing a non-toxic white powder to two Boulder Jewish organizations.
The Daily Camera reports 34-year-old Jeffery Klinkel pleaded guilty March 30 to menacing and using a hoax chemical or biological weapon. He is scheduled to be sentenced on the felony charges June 1.
Prosecutors say employees at the Boulder Jewish Community Center found a letter April 6, 2015, with white powder and a note that said, "This Goyim is enjoying the blood of her enemies for Passover." Shortly after that, employees at Congregation Har HaShem found a letter with white powder and a similar note.
The white powder in both envelopes turned out to be corn starch.
Klinkel's fingerprints were found on both of the suspicious letters.
