The family of the late hip-hop executive Chris Lighty isn't satisfied by the New York Police Department's investigation of Lighty's death.  Last year, Lighty was found dead with an apparent self-inflicted gunshot wound to the head.  .

In a statement, attorney Scott Leemon says a private investigation shows the "NYPD did not do a thorough investigation into Chris' death." The investigation reportedly revealed that the Medical Examiner never tested Lighty's hands for gun shot residue. 

Leemon also claims the gun found at the scene was not tested for DNA.  Following the investigation, Leemon and Chris' mother Jessica Brooks are urging the Bronx County District Attorney's office to launch a formal investigation into Lighty's death. 

To get the attention of the Bronx District Attorney, Brooks asks "everyone interested in justice" to sign an online petition calling for that investigation.
