Hmmm. Well if the cops are calling you that means they have evidence that you hit and run. The misdemeanor has several levels but if you ignore them they will issue a warrant and that gets messy. I'm not sure why your attorney told you to ignore them but that won't make them go away. I'm surprised they aren't just stopping by your house. Maybe they have but don't know you are at your parents' house. Either way, they have you. If it was a hit and run, parked car, no one in it, its a pretty low level misdemeanor here in the US. But if a warrant is issued you change the game. Get a different attorney first then face the music.
I'm sorry for your loss. Death is hard to handle but it is no reason to drink. Hang in there.
