Attention, three, shoot fire.

A suspicious fire swept through an apartment killing two young women.

The cause of the fire and the identity of the victims were unclear.

Belonged to 29-year-old Laura Watson-Dolton, a paramedic who had come to Iowa City to visit her cousin.

She had really loved the town and it was St. Patrick's Day.

And I think because it's a college town, sort of a great party atmosphere for St. Patrick's Day, she decided to go there and visit friends.

The second victim matched the description of a woman who had been reported missing.

She was 27-year-old Maria Lainer, an environmental scientist who was in town on a business trip and was staying at a nearby hotel.

We was hoping and praying it wasn't her, but back of our minds, we kind of knew what was.

They had found her blazer in a parking ramp and it hadn't been...it had been driven for a while.
