Seems like his conviction is true.

Looks like it might be true. But the ages are all over the place. When I looked, 1994 articles have him as 39. The 2000 post has him as 52, and the death notice has 49 (8 years later).
That second link shows Ronald Barbour to be 52 at the time in 2000, but the obit above shows him as 47.
In the Obit it says age 47, in that about forums link they say he’s 52.
