The murder trial of the two men in June 1990 led to the trial of van Tongeren and the five other ANM members being aborted due to the media atmosphere at the time. At a second trial in August 1990, six members of ANM were found guilty, with van Tongeren was sentenced to 18 years on 53 counts. Van Tongeren was sentenced "in absentia" due to a hunger strike that commenced a few days into the trial. The two men who murdered David Locke received life sentences.
