search gregg's house and came up empty. >> we were never able to locate a 12-gauge shotgun at his house. we were also looking for nel -- any 12-gauge slugs, ammunition, that kind of thing. we never found any of those items in his residence. >> they also found that gregg wore shoes two sizes bigger than the shoe impressions found at the crime scene. and police found no green overalls or hunting outfit like the one johnny described seeing on the night of the murders. with no other viable suspects, police were starting to worry that the murders might never be solved. i've lived my whole life here in fairbanks, alaska. i love the outdoors, spending time with my family. i have a family history of prostate cancer. i had the test done and that was when i got the news. my wife and i looked at treatment options. cancer treatment centers of america kept coming up on the radar. so we flew to phoenix. greg progressed excellently.
