This is a tough one to research because its name is the same as a commercial US Gold game and no PD library stocked it as Crime Wave was available directly from the author. I've searched online but sadly found no downloads or information... But I have written and posted a letter so let's hope he is still living in the same house!
Update: I've managed to contact him and these are the updates to my Dillon chase...
June 2016: This is the date I originally posted the letter!
Feb 2017: Sadly, I never received a reply to my letter. (I later found out that he had moved!)
July 2017: I managed to contact Dillon online and he thinks his disks are still in storage :-)
Oct 2017: Nothing turned up there, but he now hopes that those disks are in his attic.
April 2019: I've sent Dillion another message but sadly I've heard nothing back. I hope he's okay but I'm now starting to think this piece of ST history is now lost forever. Perhaps I should give up? I am gutted :(
