notorious b.i.g.It's been nearly 15 years since the murder of 2Pac and subsequent murder Notorious B.I.G., but the subject is still a hot topic for anyone who cares about hip-hop. Whether it's urban legends that the rappers might still be alive or the vast conspiracy theories concocted by fans from both coasts, there's something about these unsolved cases that still lives on in our imagination even as we continue to mourn the loss of two of rap's brightest stars.

That's not to say that no one has tried to truly get to the bottom of it, though. One of the biggest investigations into the life and death of the rappers comes in 2002's 'Biggie and Tupac,' a documentary following director Nick Bloomfield through Los Angeles and Brooklyn to seek out the truth about their murders -- now available free online, courtesy of our friends at SnagFilms.

While no one's willing to admit to foul play, both east and west coast police departments, along with Death Row records head Suge Knight -- all whom came under fire for the murders -- agree to be interviewed for the film.

While it's starting to seem like no one will know the truth about what really happened to Christopher Wallace and Tupac Shakur, films like 'Biggie and Tupac' are constant reminders of both the crushing loss of two titans and the never-ending questions that have yet to find answers.
