INDIANAPOLIS (AP) — Hundreds of people have turned out in Indianapolis for the funeral of a couple killed in a house explosion earlier this month.

According to the Indianapolis Star, Monsignor Tony Volz told mourners Monday there’s no way to understand the deaths of 34-year-old John Dion Longworth and 36-year-old Jennifer Longworth.

The Nov. 10 blast that flattened their home and killed them devastated their neighborhood. Its cause is still being investigated.

Jennifer Longworth taught second grade at a Greenwood school. Each Christmas, she gave her students hats and scarves that she knitted herself.

Her husband was director of product development and technology at Indy Audio Labs.

WISH-TV reports the crowd at the funeral is so big that cars overflowed the church parking lot and lined up bumper-to-bumper in surrounding streets.
