Duluth, MN – Stephanie Lynn Mattinas is behind bars for allegedly stabbing her sister in the face and beating her boyfriend with a baseball bat after catching the two in bed together.

Police were called to the home Tuesday afternoon on a report of two females fighting – a man who lived in the apartment below said the fight caused pictures and other items to be knocked off of his walls.

Inside the apartment, officers found broken bottles and shards of glass all over the living room floor. A bedroom door appeared to have been ripped off the hinges and Stephanie’s 24-year-old sister was found on the floor…her face covered in blood. She had a large stab wound on her left cheek with an 8-10″ piece of wood trim sticking out of her face.

The victim told police she had been beaten by her sister. Stephanie first attacked with her fists, punching her sister more than 15 times, before getting stabby with the wood trim. The woman was transported to the hospital where the wood had to be surgically removed.

When questioned, Stephanie told police she found her sister in bed with her boyfriend and just “snaked out.” She apparently beat the crap out of the boyfriend with a baseball bat, forcing him out of the apartment before turning her anger on her sister. A preliminary breath test revealed that Stephanie was more than three times over the legal limit to drive at the time of the incident.

Stephanie, 26, was charged Thursday with first-degree assault for inflicting great bodily harm on her sister and three counts of second-degree assault. She’s being held at the St. Louis County jail with bail set at $75,000.

    Idk man, I’ve been cheated on before …and well if I ever had caught him in the act….I’d probably would have gone to jail too. Especially if he was fucking my sister. OUCH and Motherfucking OUCH.

    When I caught my ex (now lol) husband at his mistress’s house I kicked over a solid oak coffee table that flipped in the air before it landed. Hard. I was wearing Ugg boots and got painful bone spurs on the top of my foot that hurt for a year after….my own karma haha.
    I wasn’t wasted, however. I guess my point is, you walk in on something like that, the extreme anger and hurt give you more strength- I would imagine it’s adreneline. In the end, my ex wasn’t worth all the hell I went thru- and my guess is neither is this guy. I can’t even imagine the other woman being my own sister though- that’s horrible!! I guess once all the spliters are out of her face, she’ll decide it wasn’t worth it also……

    Her sister and her boyfriend can’t really be “surprised” by her response – this crime of passion crap happens all of the time – either don’t cheat or be more careful when you do. This crap happens all the time on Jerry Springer! She could have gotten a free trip to Chicago if she had only exercised a little more self-control! Then she could have beaten the crap out of her sister and boyfriend all she wanted without having to worry about criminal charges.

    I wonder if the guy did the “rodeo” position when banging the sisters. It’s supposed to feel real nice, but I wouldn’t risk it for reasons outlined in this story.

  • Parrot Toes

    She should have shoved the wood trim up her sisters ass and the baseball bat up the boyfriends. Better yet, let them both share the bat – one on each end.

    Man, the saying “There but for the grace of God goes me” is like a neon fucking sign right now!
    I was upset enough when I found out my fiance` tried to break up with me to fuck some fat, ugly 20 yr. old floosy that same night (he figured if he said we were broken up, that made it so!)
    Had I come home the one night he *did* fuck her in my bed and caught them?? O.M.F.G. Guess I’d be hoping they let me have computer access in prison to keep up with the DD! lol. Not sure who I would have killed first, though. Probably him. And, because I *did* have email conversations with this ho, I KNOW I would have killed that smart mouth, disrespectful little bitch as well! Instead, I just embarrassed the fuck outta both of them on Facebook, Myspace and emailing the cunts boyfriend while a friend emailed her church :-) Karma has a name – and it is “Kryssa”
    Funny… within a few months she transferred to a college out of this state. *grinz*

    Word. Cheating often does strange things to everyone involved. Back when I lived in the ‘hood, our neighbor behind us was this GHETTO broad named Tenecia. She was aggressive as is… she wanted to box me over a parking spot. One night, her brother came over with, I guess, his mistress. His girlfriend showed up flipping out, and Tenecia… stabbed her in the neck with a screwdriver.

    I kind of miss the hood. BUT, the moral of the story is, if you catch someone cheating, just walk away. The situation created by sticking around is explosive and you never know who will get hurt. Just ask Joey Greco.

    This is a woman who does it right. It’s never a good idea to stab someone in the back because someone else might take the credit for your work.

    I am not condoning what she did but her sister did deserve an a$$ whooping for this one. Stabbing her was overkill. Boyfriends come and go, family is forever!

    My ex fucked my aunt, the best revenge was telling EVERYONE! And pretty much, never, really speaking to either of them again.

    if only that wretched skank of a sister had that same attitude.

    the only disappointing part to me about this story was that she was drunk.

  • Anonymous

    While I completely agree on beating the ass of the bf, I don’t understand what beating the sister achieves? Two slaps & not talking to her again would completely suffice. Heck if I needed money too I’d ask her to give me all she has since she “took” something of mine. As for the POS bf, if he cheat he ain’t worth two sticks rubbed together.

    I cannot figure out what was going on in the sister’s mind. I can’t even imagine sleeping with a guy that my sister had broken up with years before. The idea that a man has had his junk inside my sister is pretty much the quickest turn-off for me. I can’t even imagine kissing my sister’s ex, just because I can’t help but think of where those lips have been. BARF! I love my sister, but in this situation, sharing is NOT caring.

    oh. my. god.

    i’ll just take this time to mentally vomit …

    thank god for every melted barbie. for every rock thrown at me. for every fist fight. for every time i didn’t have anyone to play house (unless by brute force). for every night spent in my own room in silence (while my bro’s shacked it up giggling and talking all night). for every piece of gum stuck to random pieces of clothes. every bug, every spitball. every bald doll, every punch, kick, bite, slap, every time i couldn’t beat ganon and threw the controller to my brother….

    every christmas i didn’t have to share my toys, clothes, perfume, make up, hair things, space, ROOM, BOYFRIEND, LIFE – I’M SOOOO GLAD I DIDN’T HAVE SISTERS!

  • dr.awkward

    My brothers have a chick “in common”. There was a number of years between the events, and no hard feelings that I could tell, but still… ew.
    The girl isn’t even all skanky and gross, she’s actually real sweet and we’re fb friends even though she’s no longer banging either of my siblings. But still… ew.
    Then again, it was my oldest bro who went for the sloppy seconds, and this wasn’t the first or only thing he’s done in the name of booty that’s made me go… ew.

  • Zibarro aka Kryssa

    I think the anger towards the sister would be greater – she broke a solemn, sacred trust. If my sister had done this, I doubt I would have gone to this extreme… but I know the pain *she* caused would be much greater than the pain *he* caused.
    I’m guessing there’s been some angst between these sisters for a long time… which would explain why one had no qualms about screwing her sisters boyfriend.. and the other had no qualms about getting stabby on her sibling.
    Many/most guys think with their peckers – sisters/family are supposed to think with their hearts. Seems “hearts” were severely lacking in this family. Maybe peckers, too.. since they had to share one, lol.

(I may never march in the infantry, ride in the Calvary, shoot the artillery; I may never zoom for the enemy, but I’m in the Lord’s army!).

    Which gay pride? I may have seen you there! ;)

  • http://www.facebook.com/people/John-House/1011555524 John House

    LOL, well since you’ve been to gay pride then I’m sure you’ve seen all of the funny straight people who go there to watch the naked, the horsey (I can’t imagine walking around with nothing but a human-shaped bit, hooves and a horsehair butt plug on myself, but I’ve got pics of it!) and the draggy party on.

    I’m not one of them funny straights though…bi and quite proud, even though my girlfriend thinks I’m as gay as a rainbow-shitting unicorn. I’ve been to the San Francisco Pride just about every year since 1998, and I try to make it to Folsom…and every once in a Blue Moon, Dore Alley.

    Now that I think about it, I think I got the Crawford shirt at Folsom/not Pride. They had a ton of awesome shirts like that.

    BI? Doesn’t that border on wantonous (made up that word myself) selfish behavior? Honestly, man, you are cutting the chances for straight men, straight women, gay men, and gay women! AND no guilt? It is one thing to increase your chances for a Saturday night date, but NOT at the expense of your fellow sexual creatures (humans only, please!). I can only begin to understand your behaviors, but where they may go leaves me faint in the darkest of ways. Repent! Repent now!

    Think about this: Were your parents divorced and you caught in a violent struggle for custody? Did someone touch you? Was your mother a strong figure while your father was weak and obedient to his woman? Did you witness, as child, adults having sick and animal like sex?

    Here on DD we do not believe for a moment (not a single moment) that one becomes sexually selfish because that is just the way he is!!! It is not your fault. Pray. Pray now. God save your soul.

    BTW I would love to see some (or all) of your Folsom Street Pride pics.

    My ex husband cheated on me and I did a whole lot of really mean shit. I never stabbed anybody but i did dismantle a boat with a lead pipe, along with a flow bench and did some pretty awesome body work to a Chevy pickup truck. i did however tell my ex to come get these items because I really couldn’t be responsible for their safety or his for that matter- guess ya better come get this stuff when I’m not around or you’ll be next. LOL
    But to screw your sister’s boyfriend, she had to know there would be massive trouble.

    Ha ha, yeah, I’ve heard that “zomg bi, you selfish twunt!” stuff before. It’s only selfish if you’re carrying on seriously with multiple people who expect you to be faithful (but isn’t that true of non-bi people too–selfish straight or gay people “cheat” all the time). I’m bi and have had relations (ha ha, I love that term…”relations”…like I could replace the word with “formal tea dates” and it’d still be valid) with both men and women, but I’ve happened to settle down with a woman. To me, it really doesn’t matter what kind of erectile tissue you’re sporting, it’s all sexalicious.

    I wish I had those photos uploaded, but they’re buried in one of my old, virus-ridden computers that I refuse to get rid of even though it doesn’t work properly. I promise to make it to Pride this year though to take new ones with my new camera. ;)

    Sounds reasonable to me.  I would stab my sister in the face if she fucked my boyfriend, and I’d surely beat his ass with a baseball bat.  Only I’d probably be getting charged with homicide  XD XD
