legal advice?

the love of my lfe passed away in may from a heroin overdose does anybody know how I can get the person who did this he died at his house?

I'm sorry. Your friend can be the only one responsible for overdosing on heroin.
If the district attorney is not pressing criminal charges, I doubt there is much you can do. Do NOT pursue private vengeance: people who are involved with heroin are not kind, gentle people who will react well to accusations or threats.
Depending on what state you live in. Some states have laws that can hold someone responsible for manslaughter if they furnished the illegal drug to the "victim". You will need to contact your local prosecutor and find out the law where you live and see if the crime was committed. But, if your friend died just because he was using drugs and not something furnished to him by the other party, that party can't be held responsible just because he happened to die at his home. Sorry for your loss.
watch it you may be next when you start messing with dealers.
