WOW, Sheriff Eddie Guerra of Hidalgo County, TX was mailed Ricin.

I can confirm that envelopes, containing the deadly toxin ricin, was mailed to me and three of my detention staff. At this time due to a active federal investigation I cannot make any further comments but a media release will be sent out tomorrow. No injuries were sustained
