Police questioned a young man as a murder suspect in the case but could not proceed with criminal charges because the three surviving victims did not want to "out" themselves by testifying against him in court.[1][15] Among the stabbing survivors were a "well-known entertainer" and a diplomat.[16][17] The suspect cooperated with police during his interview but he never admitted guilt for the murders and attacks.[1] Officers stated that they strongly believed that the man in question was responsible for the crimes, but he was never tried or convicted because of the survivors' refusals to appear in court.[5][17] To date, the suspect never has been named publicly or apprehended; very little information is available about the crimes.[1][18]
