Joseph Slattery, 25, of Mokena, had drugs and alcohol in his system and a 1-year-old in his car when he crashed into an oncoming car Sunday night, killing two senior citizens, according to a report by Sun-Times Media.

According to the Sun-Times report, Slattery was driving a 2001 Chevrolet Cavalier south on U.S. 45 near Peotone with a 24-year-old female and a 1-year-old male passenger on Sunday. Shortly before 8 p.m., he crossed the center line and crashed head-on into a northbound 2004 Cavalier, the report said.

The Will County State's Attorney's Office could not be immediately reached for comment Monday night.

Illinois State Police are investigating.

There really is no update as of right now. It has been a long, and painful journey. I can tell you though, that we seem to be close to some sort of resolution.

I believe that he has been sentenced does anyone know for how long, and exactly what he was found guilty of?

He hasn't been sentenced yet, that won't happen until later this month.

First of all Im sorry for you familys loss! But I worked with this young man, for a long time a few years before this happened! He is a kind decent kid!! He made a mistake, it was an accident!! We all will be judged in the end. I did read comments, blood alchol, not a lot in his system. Also it is true drugs do stay in your bloodstream for a lomg time! GOOGLE IT! He pled guilty! He could have dragged this out for years, with going to trail, with some high payed attorneys, but he pled guilty! What more do you want from him, he will go to jail, does that bring anyone back? Like I said I know this kid, Im old enough to be his mother. He does have a heart, and has been hurting over this for a long time! Are all of you perfect?? Never made a bad choice?> Never made a mistake? A little forgiveness goes a long way!! Belive me My family is trying to forgive someone who pulled out and hit a family member on his Harley and almost killed him!! But we do understand it was just an ACCIDENT!

Hey tax payer, he did drag this out for almost 2 years. Just because you worked with him, and know what the article tells you, does not mean you understand the case. How do I know all of this? Oh because I am the grandchild of the women he killed, and I attended well over 20 court dates. Each one a constant reminder of the horrible crash, that took my Grandma and Great Grandma's lives! Now imagine if someone (having had a BAC over the legal limit) plowed head on into 2 people you loved? I don't wish that kind of pain on anyone. There is no victory here. No body wins. The Slattery's lose a son for the next 12 years, and my family lost two amazing women FOREVER. I understand that people make mistakes, but for every action there is a consequence.
