Who is Eli Rochert?

Jodi Picoult's Second Glance, set in Comtosook, Vermont, is centered in the atmosphere of conflict between a group of Abenaki Native Americans and a developer called Redhook Group that wants to build a strip mall on the group's burial ground. When supernatural occurrences start getting in the way of the construction workers building the mall, Redhook Group brings in Ross Wakeman to figure out what's going on. 
In the story, Eli Rochert is one of multiple side characters that Ross gets involved in his investigation. Eli is a police officer who happens to be half Abenaki. He was divorced by his wife, and in his dreams he now sees a woman that he has never met before. This woman turns out to be Ross's sister, Shelby.
