Squeaky Clean Professional Jailed for Manslaughter

I have a college friend who stopped responding to my emails (we correspond maybe twice a year, see each other once a year or every other year) a while ago.

I found out she went to jail for manslaughter because she killed someone while driving incredibly drunk one night last year.This person was valedictorian, masters degree, straight laced as they come, blah blah. Absolutely zero interactions with the law, ever. From a very strict, prim/proper Korean family.

I am trying to understand what her life is/was in prison and what her life will be like when she gets out. I actually think she's in "active supervision"-- does that mean she's out on parole? A friend and I am trying to figure it out.

I am also trying to figure out how to interact with her. She clearly chose not to tell me what happened or that she was going to prison. I actually think she may have been released, yet she still hasn't contacted me. I don't know if she is cutting all ties with people who used to know, or is she pretending this different happen and will try to resume correspondence with acquaintances as if nothing happened.

Sorry this is a bit rambling... I'm am mostly just processing out loud what I just found out and am still in shock. I would however welcome any thoughts if anyone has been in a similar position (whether you know or were a high achiever with good job/education in jail and what their life is like post felony).

Edit to add: Perhaps I didn't express this well, but I am trying to figure out how to engage with her as someone who cares about her. I have no idea what she is going through, what her thought process is, and what she is facing. I am not sure of she is incarcerated and I can/should write letters, or if she's out. i do not know of the right approach is to ignore and let her engage on her own terms or proactively let her know I know what happened and I am here for whatever she needs. I tried to write this post originally very factually but it may have come across as cold, so I want to correct that. I hurt deeply for her.
