Gov. Phil Murphy and the NAACP are weighing on the actions of two Bridgewater police officers who sparked controversy while breaking up a mall fight. Michelle Charlesworth has the story.

The Medical Examiner's Officer did post mortem examinations on both, exhuming the grandmother's remains.

The cause of death for both individuals was determined to be acute thallium poisoning, and both were ruled homicides.

Thallium is a lethal metal used in the manufacture of electronics.

Both poisonings may have occurred at the family home in Brooklyn, on 65th Street in Bensonhurst. Each time, medics raced to the apartment with doctors later unable to save them.

Detectives are now interviewing the parents, other family members, and anyone else who may be involved, but the remains a mystery.
