The mysterious drowning death of a San Antonio man, in Huntsville's state park, was caught on tape.
A camper at the park happened to catch the incident on camera. Police are reviewing that video hoping it will reveal more clues about why Raul Ramirez refused help when he fell out of his canoe on Sunday.
Investigators believe alcohol was involved. They suspect the drinks mixed with the cold temperatures of the lake water may have played a part in his death. Toxicology reports for Ramirez have not come in yet.
