INDIANAPOLIS (AP) – Hundreds of neighbors and relatives walked the streets of an Indianapolis subdivision hit by a large explosion two years ago before gathering for a ceremony remembering a couple killed in the blast.

Luminaries lined the sidewalks of the Richmond Hill neighborhood Sunday night and others formed a large cross in the driveway to where Dion and Jennifer Longworth's home stood before a neighboring house exploded on Nov. 10, 2012.

Emily Voss tells WRTV the neighborhood gathering is a sweet way to keep memories of her brother and sister-in-law alive.

Neighborhood resident Robert Stevenson's musical group sang during Sunday's vigil. He tells The Indianapolis Star the explosion brought the neighborhood together.

Three people are awaiting trial on charges that they rigged a natural gas explosion to collect insurance money.
