Smiley Face Murders

A group of private investigators say they're able to link up dozens of seemingly unrelated deaths of college men through a common clue: Smiley faces found near where the drowned bodies were found.

The deaths (murders?) all share common traits: Well-liked, athletic college guys who drowned mysteriously, usually disappearing after a night of drinking. The drownings are usually chalked up as accidents, but two former New York cops say they've found links that make them look more like murders, and they hypothesize that a sinister group of killers is behind them all.
