He was best known for Deadly Prey and his recent sequel Deadliest Prey; other notable movies included Final Sanction and White Fury to name but a few.
There are several posts to David’s Facebook page stating that he passed away over the weekend after a long battle with failing health.
We don’t know the official cause yet but it will likely be officially announced soon.
Prior’s most recent film Assassin’s Fury was apparently in post-production.
RIP Mr. Prior and best wishes to all the friends and family at this time.
