Although the motive for the murders was never fully established, it is a popular topic of debate among fans. The most common theory suggests Sikh militants orchestrated the murders.

The Immigration and Refugee Board of Canada commissioned an inquiry seeking information on the killings, on the basis that Chamkila and Amarjot were killed by Sikh militants.

The inquiry did not turn up any useful information despite consultation with several sources.

An Indian news and editorial outlet named the assassination of Chamkila as one of the most controversial unsolved murder cases in India.

Despite his death, Chamkila's popularity within Punjab and with the Punjabi diaspora continues to surge.
