In January 2008 Jameson reported that Joe Barnhill Jnr had a history of sex crimes and that at least one victim was a child. She said the victim was 7 or 8 and that her family went to police at the time and accused Joe Jnr. They say he was brought in for questioning at the time. Although there was never a prosecution it was all documented. After JonBenet’s murder the victim and her family again went to the police to report their concerns about Barnhill Jnr.
Joe Barnhill Snr was interviewed by Detectives Thomas and Gosage on December 31 but Joe Barnhill Jnr wasn't questioned until late January. Detectives Thomas and Gosage were reportedly rough with him until he assured them he and his wife Sandy were in Kansas on that Christmas night with friends.
The friends wouldn't back up the alibi and then Joe Jnr changed his alibi saying they spent all Christmas day at home, which was some way out of Boulder. Joe Jnr claimed had he lied to police initially because, he says, they didn't want Joe and Betty Barnhill to be upset that their son had not gone to visit them.
His DNA was tested and the results obtained January 30 1997. His DNA did not match the fingernails or the panties bloodstain
But that does not matter. Since it is likely that there were multiple intruders these results just rule him out as being the person she scratched and the person who orally assaulted her. Barnhill Jnr might 'just' have been an onlooker
How the investigation into him proceeded after his test results is unknown. However apparently he was still on the police suspect list as late as June 1998 as evidenced by Steve Thomas' statement during his depo on September 2001:
10 Q. Let's refer to it as the June
11 1998 VIP presentation so we know what we're
12 talking about. Did, in fact, the detectives
13 during that presentation present a long list
14 of suspects who had been considered and
15 dropped, including Randy Simons, Kevin
16 Rayburn, Bud Henderson, Linda Hoffman-Pugh,
17 Joe Barnhill and Chris Wolf?
18 A. I would certainly have to review
19 any notes and reports from the police files
20 on that, but that's not inconsistent with my
