I am not sure if Archbishop Carlson would have any authority if Sr. Keenan resides outside of the Archdiocese of Saint Louis, perhaps but I think not. I believe that the jurisdiction over her as a member of a religious order would be with the Congregation for Institutes of Consecrated Life and Societies of Apostolic Life rather than with any local bishop.
The others on your list, however, are not bishops. I was specifically addressing the fact that the bishops could not act as some sort of collective board in disciplining her.
Number one, it's Keehan not Keenan(sic).
Number two, Carlson does indeed have authority.
The names of the others were posted for your edification. There are a number of people who have both the authority and the responsibility to discipline her. Sadly they are all abdicating their authority and responsibility.
