Arizona Woman Accused of Killing Baby Daughter

(Phoenix, Arizona) A 36-year-old local married mother-of-nine, Nina Koistinen, has been accused of suffocating her 6-day-old baby girl.

Koistinen was arrested on suspicion of first-degree murder.

Police said Nina Koistinen told them she smothered Maya because she thought she had too many children and that she was jealous of the attention her husband was giving the newborn.

Bradley Koistinen attended his wife's initial appearance Friday and made an emotional plea to the court.

"Nina suffers from bipolar, schizophrenia and depression," he said. "And we have tried for years and years to manage it. She has been the greatest mother. We've been married 15 years. To our kids, never once has she hurt any of our kids. I see her deteriorating the last two days - her mental state. I don't know if her medication is right."

Koistinen was booked into custody with bail set at $1,000,000.
