Case 140

Richmond Hill

Just after midnight on November 10 2012, a loud and frightening sound erupted in the Indianapolis subdivision of Richmond Hill. The force was so powerful that it registered on a regional earthquake sensor and homes were left rattling from the impact. Emergency services raced to the scene but were unable to save the lives of two residents, Dion and Jennifer Longworth. 

The explosion appeared to have originated from the home of Monserrate Shirley and her partner, Mark Leonard. As investigators sorted through the wreckage of the once picturesque neighbourhood, the question arose – was the Richmond Hill Explosion a tragic accident or part of a deliberate attack?
