HOUSTON -- A Harris County grand jury declined to indict a pair of Houston police officers in the shooting death of a man who claimed to be an agent for the CIA.

Roland Carnaby was killed after leading police on a high-speed chase through southwest Houston on April 29. He was shot after stepping out of his vehicle before reaching under his car seat for a shiny object that turned out to be a mobile phone.

Carnaby, 52, had initially been pulled over for speed on State Highway 288. When he showed the officer an ID card that showed he worked for the CIA.

Minutes later, Carnaby took off.

The chase ended on a Loop 610 feeder road near the Galleria. A Houston police sergeant and a patrol officer were no billed by the grand jury on Thursday.

The CIA maintains that Carnaby was not an employee or associated with the intelligence agency. Houston police said they have not been able to find any evidence that would back up Carnaby's claims that he worked in the intelligence community.

Carnaby's family, however, maintains he did have some sort of association with the CIA. Carnaby's wife has also sued the Houston Police Department for shooting and killing her husband.

Nevertheless, even some of Carnaby's staunchest supporters back in April are thinking differently now.

“Some of the stuff is starting to make sense in my mind that he wasn't a CIA agent,” said car dealer Alan Helfman, who wasn't alone in thinking Carnaby really was some sort of intelligence officer. "So did a lot of other people high up in law enforcement in intelligence, they believed him also."

Helfman says he's questioned many of Carnaby's friends and other sources.

Nothing is adding up and he said there's an explanation for all the CIA paraphernalia Carnaby toted around.

"These cups and stuff nice things he was wonderful he always brought me neat stuff, but so many of them, you can get from walking into the store in Virginia (it) is as easy as that,” Helfman said. “Or a picture like that (standing) on the CIA seal. Anybody can walk in there and take a picture. I didn't know that."

He also still doesn't know why Carnaby would run, but an attorney for Carnaby's wife has an idea.

"Roland Carnaby was a contractor for the FBI, the CIA and the Secret Service and he could have had sensitive information in there that he didn't want to get put in an impound lot,” insisted Randall Kallinen.

Even so, as far as an agent with the CIA? No one has confirmed that and likely never well. That's what now has some of his closer friends wondering who Roland Carnaby really was.
