TOPEKA (AP) – The Kansas Corporation Commission says it needs more time to investigate a house explosion that killed a Topeka woman.

The KCC was to present its findings Tuesday in the January blast that killed 81-year-old Lucinia Tolliver. But the corporation says it needs additional time to complete the investigation.

Investigators have said digging in a yard west of Tolliver’s home caused a natural gas service line to separate from the main line underground. The natural gas migrated into Tolliver’s home, which exploded.

She suffered severe burns and died about a week after the explosion.
