Reminds me of the case of Delano Burkes. He left a bar, was seen stumbling on camera, and then they found him in the ship channel.
Burkes' body was found Friday in the Houston Ship Channel, officials confirmed, about 12.5 miles away from where he was last seen alive.

As I mentioned in the threads about Delano, I lost a middle school friend when his frat brothers abandoned him at a Nuggets game in Denver because he was too drunk. He ended up dead on the railroad tracks in eastern Colorado.
The debit/credit card being found seems to be a very valuable piece of information. It looks like it was found near a homeless garbage dump near the river. I doubt that it washed ashore as some have speculated, but it would appear to also have been dumped in the garbage pit by the nearby homeless population.
