Charles Hanson, 42, and his wife Svetlana Hanson, 24, were killed on August 10, 2010, at their home in Eagan, Minnesota.

Bhattacharyya was identified as the shooter and was arrested and charged in connection with the deaths.

Are there witnesses or neighbors who remember activity at the Hanson home that morning, or anyone with information about prior threats or confrontations involving Bhattacharyya?
