Forrest “Butch” Bowyer was stabbed in the neck and his 12-year-old son Brett shot dead by robbers in Alabama in February 2002.
The victims were buried in shallow graves - but Bowyer somehow managed to claw his way out.
Bleeding heavily with his throat cut "from ear to ear", he crawled to Highway 431 in Seale, Russell County, for help.
The officer on camera can be heard saying: "I got a man that’s been cut to hell and said his son’s been shot 3 times.
"[The son] is buried in a grave down here at Uchee, and he wants to go get him.
"He was buried and dug himself out, this is a bad one."
In the video, obtained by WVTM-TV News Leader 9 , the officer asks Bowyer who attacked them, to which he responds multiple times, "Jim Brooks".
Bowyer can be heard telling the patrol officer that the killers would likely be back at his home "trying to get some more money".
Brooks and accomplice Michael Carruth were later arrested found guilty at trial.
Both are now on death row, WVTM-TV reported.
Russell County sheriff Heath Taylor told the news channel: "It’s crazy to think about he [Bowyer] survived that night.
"Not one single time do I pass this area, where this occurred, that I don’t think about that case."
