I remember it being on TV around 2003-2005, I don’t think it was new at this time, but it definitely came out in the 90’s to that time. There were these prisoners in the desert, or near it and a zombie like prisoner was killing them with a pickaxe? I think it was one of the correctional officer’s dad or something. And he realizes it at the end, then something with blood seeping into concrete or something. The dead prisoner guy almost looked like Michael Myers, but his face was dry and dead looking. I think the correctional officer was a Hispanic actor.
