Wife: Hubby's Ex Tried to Assault Me With Peanut Butter Peanut butter-smeared letter could lead to charges By Evann Gastaldo, Newser Staff Posted Jun 13, 2011 3:42 PM CDT 8 comments Comments Can peanut butter be used as a weapon? (©koocbor) (Newser) – Anyone might find a letter smeared with peanut butter a bit odd, but one woman considered it … assault. The woman says her husband’s ex-wife sent him the letter, and since she’s highly allergic to peanuts, she believes it was actually an attempt to harm her. She found the oil-soaked envelope in her mailbox, with a note on the outside indicating that peanut butter was inside. The woman wants authorities to file assault charges, but police say it may not be possible without proof intent to harm. The ex-wife’s excuse? She says she simply wanted to keep her ex-husband’s new wife from reading mail that was none of her business, the Battle Creek Enquirer reports. A county prosecutor’s office is reviewing the case.
