RUMOR has it that he was in the Walmart parking lot and was being chased.
Brandon left his house at approximately 11:54. He called Kyle at approx. 12:38 to say he ran out of gas. That is about 45 minutes. I drive that highway all the time. It takes 20-25 minutes from the OTHER side of San Angelo to get to the Stripes at Bronte. Brandon was around 4 miles south of Bronte. It does not take 45 minutes to get to where he ran out of gas. With that said, he had to of driven somewhere else in San Angelo before he took off toward Bronte.
Now suppose he met someone in the Walmart parking lot for whatever reason. They talked or whatever and at some point they got in an argument of some kind. Remember, he was already mad when he left the house so I am sure he was not very happy. Something went wrong at Walmart and a chase ensued. He started running and took off out of town thinking they would not follow. He ran out of gas, called his brother and while waiting for Kyle, the other guys caught up with him, he "got chased into the woods", he "got one of the guys" called 911 and the rest is a mystery. My theory is they caught up with him and did him harm. JMO
