The shooting had many of the characteristics of a professional assassination. Although the attack took place on a busy London street, the police struggled to find witnesses willing to come forward. Purewal's murder remains unsolved. Also unsolved is the murder of Tara Singh Hayer, a close friend of Purewell and fellow Sikh journalist from Vancouver. Hayer was murdered in a similar manner to Purewal in 1998. Several journalists and members of the Sikh community believe the two were murdered to prevent them from testifying against the terrorists responsible for the Air India bombing. Another theory is was that Purewal was murdered by a family member of one of the rape victims whose identity he revealed in Des Pardes. Purewal upset Sikh community members by publishing the names of rape victims, their assailants, and adulterers. He both owned and edited the paper, which he started in 1965. Police sources said the rape reports were thought to have been based on court cases but because Des Pardes was at the time available only in Punjabi, authorities were initially unaware the that newspaper was publishing information in breach of court rules barring the disclosure of rape victims identities.
