A Kansas man convicted of killing an 18-year-old woman and two-year-old twins she was baby-sitting in 1984 is asking a court to order a DNA test in the case.

Arnold Ruebke Junior's lawyer filed a motion Tuesday asking Reno County District Court to allow testing of DNA evidence collected during the investigation. Such testing was not routine in 1984.

Ruebke was convicted in 1985 of murdering Tammy Mooney and the
two boys, Andrew and James Vogelsang, in Arlington and was sentenced to 12 life terms.

The motion says evidence suggests other suspects, and that DNA testing might establish Ruebke's innocence.

The motion points to Mooney's live-in fiance, Bill Lorg, who
died in 2003. The motion claims investigators collected evidence
containing Lorg's DNA.
