That was my initial thought.  The next thought was...why was she the only one who got away?  Was it a sacrifice? Did she sacrifice her son and perhaps husband?  Gotta be like Columbo with these things -- look at different angles, even if they don't seem likely. Also, Hollander and Angelucci were both men's rights activists.  Angelucci -- Angeles...the coalition he created was based in Los Angeles.  Add to this the 666 symbology... Maybe sacrifices.
