Im Looking for information concerning the whereabouts of William Banks after the posse broke up. I've come to a dead end, anything would be helpful

Triplett is a fairly uncommon name. Any relation to an outlaw named Richard "Dick" Triplett who operated in the Cherokee Nation during the late 1870s and was wounded when outlaw Jim Barker was killed?

I've been researching attempting to find out more information on Deputy Marshal William Banks. It appears he worked out of El Reno and worked with Madsen and Prater. Does anyone know any information regarding his background, ancestry, or other biographical information?
