Richmond Hill (wibc.com photo by Mike Corbin)

Indianapolis Public Safety Director Troy Riggs clarified the classification of the Richmond Hill subdivision explosion probe today.

Listen:

Riggs says even though the blast that killed two and wounded numerous others is being treated as a homicide, he adds that investigators always considered it a "crime scene." Riggs says an explosion of that magnitude warranted such treatment.

However, Riggs says they're not ready yet to call the fire department's probe an "arson investigation." Riggs says he can't say much because he doesn't want to jeopardize the investigation.  He says he's working closely with the Marion County Prosecutor's office and they have the best investigators on the case. Riggs says at this point, they've determined that what happened was not an act of God and that they're being very careful with the probe.
