Search for cause of deadly Indianapolis explosion

By

INDIANAPOLIS (AP) — Two people are dead and dozens are displaced as investigators continue to seek the cause of an explosion that leveled at least two houses in an Indianapolis neighborhood and damaged as many as 30 beyond repair.

Indianapolis fire officials say they don't know yet what caused the blast around 11 p.m. Saturday.

Citizens Energy says crews haven't found any signs of a gas leak.

Officials have not released the identities of the two people who were killed. However, a candlelight vigil was held Sunday night at Southwest Elementary School in nearby Greenwood for second-grade teacher Jennifer Longworth. She and her husband, John Dion Longworth, lived in one of the homes destroyed in the blast. WTHR-TV reported that friends, family and colleagues of the teacher gathered at the school.
