UPDATE- 3-28-16

Ok, I put this together. We already know that William Reece worked on Robert Abels property which means He and Mark Stallings had to have known each other. I also discovered from TDCJ that Reece and Stallings were on the same prison unit called the Holliday Unit in Huntsville Texas. There are dormitories there, around 66 to a dorm. I am wondering if Stallings and Reece met up back there in prison and compared notes so to speak. Could Stallings be trying to confess to a few of the Reece murders? Did Reece tell Stallings about his escapades and Stallings is trying to get credit for them?

In one of Mark Stalling's letters, he talks about some kind of underground bunker about 240 miles from Houston where there were girls chained to a wall, well about 240 miles outside Houston is Denton Texas, the same city that Kelli Cox turned up missing. 

So many questions and possibilities. 

Were Reece and Stallings working together?

Will update when I can...
