Little is known about Francis Ruiz though he used to drum in the Great White touring band in 2000. Previously he played in Cynical Side.
Later he showed up in a band called Samantha 7 which featured C.C. DeVille of Poison. Unfortunately the band's tour was curtailed when Ruiz was run over crossing a street and sustained a broken leg. Tour manager Paul Woolnough deputized for the remaining dates. Ruiz decided to depart from the band in 2001.
