Description
The Richard Alfredo Case. When a Massachusetts man dropped dead of an apparent heart attack, no one thought foul play was a possibility until police looked into his girlfriend’s odd behavior in the days before his death. Controversy surrounded the case for almost a decade, which pitted competing teams of toxicologists against each other: One claimed the death was due to natural causes, and the other said it was cold-blooded murder.
