Catch a killer is a Facebook criminal investigation game, where you have to look for clues and then use forensic skills to solve the investigation.
Law Enforcement officials fear that there may be as many as 50 active serial killers in the United States. The FBI needs you and your friends to help, using the power of Facebook.
In Catch A Killer, your main task as detective is to examine the evidence for a series of cases by playing mini-games. While checking crime scenes, particular pieces of evidence are to be found on screen and clicked. Depending on the crime scene, these items can range from a ballpoint pen to a knife.
