I think that this verse is about Danny Dan one of his old friend who died in a car accident he was a hustler jay-z looked up to and he even dedicated In My Lifetime to him.

Here is an article about him:
“The one name that is a constant in relationship to Jay, from believers and nonbelievers alike, is Danny Dan—also from Bedford-Stuyvesant’s Marcy Houses. It is said that when Dan was buried in the late ‘80s, he was wearing at least $100,000 worth of jewelry. His funeral, which was talked about for five years after, was one huge fashion show. But more than the jewelry or the girls in furs is the remarkable detail that Danny Dan died with a will. "Danny Dan was a cat in the projects, coming up,” says Jay. “He was very influential in my life, but from afar. Holmes was doing it. He’d always put something away, not touch it. I was like, I need to be doing that.” Danny Dan was five years older than Jay and was know for being the kind of reckless driver who would push German sedans past 100 m.p.h. down New York’s crowded streets. “He always said he’d die in a car crash, and he did,” say Jay. “Coming back from D.C. on I-95.” Those that talk say Danny’s death left a vacancy, further south, in Virginia and that Jay moved on it, opened it up further, and creamed off.“
