Ohio LE here.
You didn't do 2 days of hard time; go to North Korea to see what hard time is. You sat in a cell and got food brought to you and watched TV. Oh, and 18 is not a "tender age." Men go to war and die for their country at 18. You were an adult and you fully knew that what you did was wrong.
You say of your revocation hearing, "I wasn't able to make it." That doesn't hold water. You didn't show up. You skipped out. Courts give continuances, and you chose to just not show up. You now have a warrant.
Yes, you made "a pretty big mistake here." The fact that you "DO NOT want to go back to jail for any reason whatsoever" is irrelevant. There is a warrant for your arrest and in order for it to be cleared, you will likely need to be arrested and booked, or at least post bond. You are also looking at contempt of court charges.
The fact that the victim is dead is irrelevant because the case is already disposed of. What needs to be addressed by the court is your probation violation. The victim has no bearing on that.
Call the court, find out how much your bond is, and then show up to pay it. You might be arrested or you may not be - oftentimes, if you show up and post the required bond there is no need to take you into custody. Either way, you will make your bond and be released; a new court date will be given to you. SHOW UP FOR THAT hearing.
Get an attorney, but there is nothing to be "dismissed." The original case is already disposed of; what your attorney needs to do is convince the judge that the probation violation is basically irrelevant today and that you should not be held in contempt (and good luck with that.)
It's going to cost you. Now here's the part I'm not sure of - but I do not believe that you are entitled to have an attorney appointed to you if you cannot afford one for a probation violation. I could be wrong on that - but I believe that protection only applies to original charges. So you're likely to be paying this out of pocket.
