WEST COVINA — Officials said they had no plans Wednesday to seek charges against a man who fatally stabbed his step-father in a fight while reportedly trying to defend his mother, a cancer patient.
Mark Vansimaeys, 30, of West Covina was believed to be acting in defense of either his mother or himself when he fatally stabbed his step-father, 48-year-old Dean Franklin Ybarra, West Covina police Lt. Ron Mitchell said.
“It was a horrible altercation,” Mitchell said. Though the investigation remains ongoing, “At this point, we don’t plan to arrest (Vansimaeys),” Mitchell said.
Another man, a brother to Vansimaeys and step-son to Ybarra, was present at the home Monday, Mitchell said. What role he may have played in the incident remained under investigation.
The dead man, who was listed with coroner’s officials Wednesday as Dean Franklin, apparently died from “multiple stab wounds,” Ed Winter, Los Angeles County Department of Coroner’s Assistant Chief of Operations, said. An autopsy had not yet been performed.
The stabbing was reported shortly before 7 p.m. Monday when someone called police to report domestic violence at a home in the 700 block of East Merced shared by a husband, wife and step-son, West Covina police Cpl. Rudy Lopez said.
Both Vansimaeys and Ybarra were found injured inside the home, he said.
Domestic violence is tragic and especially when Dean’s intention was to visit his wife suffering from cancer. If this was truly an act of self defense or protection may Dean’s family find peace!
To my cousin Dino rest in peace, you will be missed greatly!
Our prayers are with you and your family
Forever loved and remembered.

I believe that although Dean’s family was not present at the time of this altercation they can provide another viewpoint of the Dean and Irene’s family dynamics.
There is just something wrong with this story! mother and 2 grown sons in the house with stepfather.You mean the 2 sons who are grown men couldn’t get the stepfather to leave or kick him out the f–king door,if they felt that their mother was being bothered by him why not hold him down on the floor while mother could have called the police!Instead it sounds like they were able to hold him down and kill him with a knife. (COULDN’T HOLD HIM DOWN TO CALL THE POLICE!! BUT WERE ABLE TO HOLD HIM DOWN TO KILL HIM WITH A KNIFE) just doesn’t sound right.Doesn’t say anything about mother being treated for any injuries? but the KILLER was treated and Dean Ybarra died from multiple stab wounds.Wow what luck for the killer.and the victim the(stepfather) probably didn’t even get a chance to defend himself.(2 brothers with a knife and the stepfather who’s going to out alive? the two brothers with the knife. Chicken sh-t cowards. I dont believe in Domestic Violence but this one just doesn’t sound right, maybe they just didn’t like the stepfather. which ever way you look at it no one deserved to be MURDERED.

To all that comment negative feedback.. ha!
You should learn to do something better with your life.
So what if there freeloaders and jobless, Your for one not taking care of them. So do yourself a favor and butt out of there business!! As for “April 23, 2009 7:17 AM A Concerned Friend said” What are you an investigator??.. Don’t speak without evidence! You may think you know someone but, you may never know there real dark side! So that should teach you to learn more information out on your dearly friends! Don’t just assume! Maybe this can teach other men not to lay a hand on a women! If anybody is a “coward” it’s those men that lay there hands on women (AKA DINO)!! I feel justice was served in each way possible! What more can i say then “Dean Franklin Ybarra” got what he deserved! Now there is peace for that family! NO WOMEN SHOULD HAVE TO GO THREW SOMETHING LIKE THAT. MAY THE ANGELS BE WITH THAT WOMEN AND GENTLEMEN!
