That's what I was thinking too, but then I realized that there's a hospital on the way from Hiney's to Hooters. However this guy got from where he was stabbed to where he was found, he had to pass right by a hospital (Del Sol Medical Center, which has emergency services available).
If it had been his friends (or some Good Samaritan) who moved him from Hiney's to Hooters, why didn't they just leave him at the hospital in between?
Weird, huh? Paging Lt. Columbo ...
Ugh, I was at the ET the other day and guess what the big sign at the front desk was? One guess. Yep, you got it. It was in Spanish informing illegals by law they could give birth there and recieve treatment without any questions.
Is Hooters closer to the border crossing than the hopsital? Perhaps his cousins merely dumped him out of the back of the pickup on their way outta the country.
