A Wisconsin woman whose alleged actions against her boyfriend’s dog sparked outrage in her community is due to go to trial in May. Authorities say Sean  Janas, 20, intentionally killed her boyfriend’s dog, Mary, in June by poisoning her with Drano, bleach and pills, and then stabbing her. She pleaded not guilty in October to mistreating an animal resulting in death, poisoning an animal, and obstructing an officer. During her arraignment, dog lovers protested outside the Wasau courthouse. Many brought their dogs along and carried signs demanding justice for Mary.

A neighbor reported seeing Janas hitting the 4-year-old lab and shepherd mix with a leash in the yard, and then hearing Mary whimpering and seeing Janas walking away from her holding a knife. In a disturbing diary, Janas allegedly described her hatred for the dog and her desire to kill her: ”I have never hated an animal so much in my life, much less hate one or beat one. But the pleasure I get from watching her whimper in pain & cry out for help as I shove drano & bleach down her throat is like no other.” According to authorities, the abuse had been going on for months before Mary finally died. In the weeks leading up to her death, Mary had reportedly been coughing up blood. “I need to find a way to kill her (the dog) without it looking like I killed her,” Janas allegedly wrote.


If convicted on all charges, Janas faces more than five years in prison and $30,000 in fines. Though assistant district attorney LaMont Jacobson considered also charging Janas’ boyfriend in the case, he determined that ”his neglect if there was any didn’t rise to the level of criminal neglect and I did not feel charges were appropriate.” Wisconsin animal rights blog North Horse reports that Janas’ boyfriend knew about the abuse but did nothing, and that Janas was only charged after he found her diary in his apartment, four months after Mary died. This information, however, has not been confirmed by authorities.
