Seeking advice regarding robbery and assault incident few years ago

Some rfder's maybe remember this, but 3 years ago when i posted about this is in scammer and warnings, I was selling a canada goose jacket online. a buyer contacted me throug kijiji and we arranged for him to pick it up at my house. he kept giving me excuses about running late and it ended up being at midnight. I was naiive and didnt take precautions, right in my own house's porch door him and his friend grabbed the jacket and ran, i chased him only to get overpowered and thrown while taking a few punches to the face and they escaped in their car. I called authorities and gave them all the emails and showed them the texts. the phone number was soon deleted/changed. a detective called me like a month later for more info but I didn't have anything else for him.



so just this week, in my first year of university, i was building up my profile on linkedin, and what do you know, i find his profile with his exact email. it states what university he goes to, what stream, his expected graduating year.



my question is, would this be useful for authorities? will they even care about such a case that was so long ago?



i just don't want this scumbag to get away free for what he's done
