A 23-year-old woman was killed and another woman was injured when an explosion rocked a housing complex in central Alberta Friday.

Innisfail RCMP said that a package arrived at the home by delivery shortly before the blast, but officers did not link the package to the blast.

The deceased woman was identified by friends and congregants of a community church as Vicky Shachtay, a young mother who was paralyzed by an earlier automobile accident.

Shachtay's aide, who was also injured in the blast, had been working at the home at the time of the explosion.

Police are currently probing the cause of the blast, and an autopsy is set for next week in Calgary.

Nearby residents of three other units were evacuated by officers Friday morning, but police said that most of the damage occurred inside one suite.

RCMP officers also blockaded the surrounding neighbourhood, which is close Innisfail's junior and senior high schools.

Innisfail is about 100 kilometres north of Calgary.
