Massachusetts jury deadlocks 11-1 on Lindsay Clancy murder trial after postpartum psychosis defense; mistrial declared after seven days. Plus: 16-year-old Timothy Hudson's cruise ship murder trial delayed due to family tension; Barry Morphew arrested for hit-and-run while on house arrest; and how the insanity defense actually works in court. The insanity defense is a legal standard, not medical; defendants must prove they didn't know their actions were wrong by society's standards, using the 19th-century McNaughton test in most U.S. courts.
