“Toxic” relationship leads to murder of California police officer

Erika Sandoval was arrested in the murder of her ex-husband — fatally shooting him a week after he posted a photo on Instagram of himself with his new girlfriend. Officer Daniel Green, 31, was killed in 2015. Those who knew the couple said they had a “toxic” relationship. “48 Hours” correspondent Erin Moriarty joined “CBSN AM” to discuss this week’s case.
