Prosecutor: Ind. blast probe 'painstaking' process

INDIANAPOLIS (AP) — The investigation into an explosion that killed an Indianapolis couple and decimated their neighborhood is a “painstaking” process with no timetable for a resolution, a prosecutor said Monday.

Marion County Prosecutor Terry Curry said police are conducting interviews based on input from the public as investigators continue to seek the cause of the Nov. 10 blast that killed Jennifer and John Longworth. Authorities have said they believe the explosion was intentional and caused by natural gas but have released no other details.
