I was driving and hit a light pole, my passenger died as result of accident , i left scene and returned 2 days later and filed a report.

Based upon the limited facts that you presented, you could possibly face traffic charges and/or civil responsibility for death of your passenger depending on whether or not you were at fault for the collision.  As to possible traffic charges, if you have not already done so you should consult with a traffic court attorney.  Also, if you have not already done so you should report the collision to your auto insurance company so that a claim representative can investigate the accident and discuss with you whether or not you were at fault for the collision.  Good luck with this matter.
