There are very few hip hop figures who remain as beloved in their death as they were alive, but The Notorious B.I.G. is one of those individuals.

Today (March 9) marks the 13th anniversary of the passing of the rapper, whose real name was Christopher Wallace. Since being fatally gunned down in 1997 after leaving a Vibe magazine party in Los Angeles, still, no suspects have been arrested in his murder.

Investigations into the murder of the Brooklyn-bred lyricist remain on-going and the wrongful-death lawsuit filed by his mother, Voletta Wallace and his ex-wife Faith Evans, against the city of Los Angeles and other defendants is also pending.

Speculation is widespread as to who was blamed for Biggie's murder. Fingers have been pointed at former Death Row Records CEO Suge Knight and Los Angeles Police Department cops.

Wallace declined to comment on the status of her lawsuit but issued a brief statement to MTV News: "I thank you for the opportunity to touch [my son's] fans and for the network's continued support of me and the family, but it's been 13 years, I miss my son, his children miss their father, and the murderer is still at large."

LAPD officers Rafael Perez and David Mack, who are alleged to have been on the Death Row Records payroll and had a hand in the homicide, have since gone to prison on unrelated charges. The LAPD is said to have covered up the dirty cops' involvement in the death of Wallace to keep from a large civil lawsuit payoff. In fact, it was proven in July of 2005 that a lead investigator in Wallace's murder case hid evidence, which caused the trail to be declared a mistrial.

The FBI, which at one point picked up the investigation, have now stopped its pursuit, MTV News reported.

Regardless, of the long-standing difficulty in bringing Biggie's murder to justice, people who loved the 'Mo' Money, Mo' Problems' rapper are choosing to reflect on the music that he left the world with.

Bad Boy Records founder Diddy said that he's planning to celebrate his friend on a day that he thinks should be a national hip hop holiday. The Harlem-born music mogul will head across the bridge to Brooklyn club, the Lab, where Biggie tunes will be played all night by DJ Mister Cee.

"It's a day to celebrate his life," he said. "It's a day to celebrate the life of the man. We done did the movie, the records. It's something that, I guess, as a label we're obsessed with: making sure people don't forget about this man in a positive way."

"March 9 is Biggie Day. ... Bump Biggie all day, feel good and positive," Diddy declared.

Biggie Day it is.
