Open source ReiserFS creator, Hans Reiser, may lead investigators to the body of his wife, who disappeared in September 2006.

A jury found Reiser guilty of first-degree murder charges in April. Currently, he could face 25 years to life in prison. Apparently after insisting for six months that he was innocent, Reiser is trying to get a reduced sentence in exchange for telling authorities where to find his wife's body.

Nina Reiser was last seen dropping off the couple's two children at Hans Reiser's home. His lawyer tried to convince the jury that the mother of two may have fled to Russia. Reiser developed ReiserFS, the default file system on SUSE Linux/openSUSE, Slackware, Xandros, Yoper, Linspire, and Kurumin Linux.

The 44-year-old claimed his wife nicked cash from his outfit, Namesys.
