DENVER (CBS4) — Three adults and two children were taken to the hospital early Saturday afternoon following an apartment fire in west Denver.

A fire department spokesman told CBS4 that crews arriving to the scene in the 3400 block of 4th Avenue quickly discovered a woman on the building’s second story.

The woman had already dropped two children down to bystanders before fire crews arrived.

Residents of the eight-family complex have told CBS4 the woman then jumped from the window herself and landed on a glass patio table.

Those residents said the woman was pregnant.

The woman suffered smoke inhalation, according Capt. Greg Pixley of the Denver Fire Department.

Conditions of those transported from the scene are not known.

Pixley said the fire appears to have started in the garden-level apartment and worked its way upward into the floors above.

Fire investigators are still looking into the fire’s cause.
