what happened to those murderes - i think lee colgan is dead?

I found this part on website covering the Helen betty Osborne murder:

Dwayne Johnston served ten years of a life sentence before being released on October 10, 1997. He will remain in full parole. He continues to live in Manitoba.

Lee Colgan died of an extended illness (probably from the drinking, but it's not been confirmed) in 2004.

Jim Houghton continued on with life. He presently lives in Winnipeg, Manitoba.

There whereabouts of Norman Manger are unknown.
