My question involves criminal law for the state of: Nebraska
This happened between myself, my roommate of 2yrs(guy) in our own apartment.
About a month ago in my apartment me and my roommate ended up in a confrontation due to what started as a verbal dispute. It escalated to the point where he swung at me, I ducked and then tackled him. Upon this I punched him a couple times in his back and his head. Cops were called by our third roommate and upon their arrival I was given a citation for Assault Misdemeanor(3rd).
Since this time as this was about a month ago, my roommate and I are both still friends, he didn't press charges, nor did he receive any injuries except a slight headache and a bruise on his back.
At my court hearing I was told I was being charged with 3rd Degree Assault and Disorderly Conduct(which I am not sure why)
My question is that at my future trial, what are the possibly sentencing? I have no criminal history at all, I do not even have any driving tickets. My friend in which the altercation was with states he is willing to help clear my name, but I am still worried about what I could possibly be sentenced.
Thanks for your help.
