HUTCHINSON — The woman injured in a house explosion last week in Hutchinson remains in critical condition, according to fire officials.

Theresa Kappel, 47, was taken to St. Francis Hospital in Wichita following the explosion and fire that engulfed her home last Thursday.

The fire at 1502 East 2nd was reported just after 2a.m., according to Hutchinson Police.

Fire crews found the house fully involved with fire venting from all windows of the structure, according to a media release.

Crews brought the fire under control in approximately 25 minutes before entering the structure to complete work on extinguishing the fire.

Investigators are still not certain what caused the explosion, but are still leaning towards a loose gas line fitting, according to Hutchinson Fire Chief Kim Forbes.
