Police say a mother was arrested in the death of her 3-year-old child

The mother of 3-year-old twins was arrested after one of the toddlers died and the other was left in critical condition after Los Angeles police say they consumed an unknown substance.

Jeff Nguyen reports from Winnetka, where the 22-year-old mother of two toddlers found unresponsive after an apparent overdose was arrested on Friday. One of the children died after being rushed to a hospital, where the second child still remains.
