A semi-creepy teaser has debuted for Unsolved Crimes, a murder mystery style game for the DS due out September 16. Check it out in the quote.

Set in New York City, players take the role of a rookie detective from a homicide division. Eight cases in the game are yours to solve, all of which revolve around a series of kidnappings and the disappearance of a woman named Betsy Blake.

The touch screen (as is shown) will be used to trace memos, marks and routes on particular items; car chases, shootouts and a quiz are other features planned for the game.
