Police conducting a well-being check discovered several bodies in an Arlington apartment Monday afternoon.   Two of the bodies were adults, two others were young children.

Middlesex County District Attorney Marian Ryan says it's a "very troubling and tragic situation."

The children were less than a year-old according to Ryan, who says the manner and means of death was to be determined by the state medical examiner's office.
