Mark Bowden wrote of real life private investigator Ken Brennan in Vanity Fair in December of 2010. The story was titled "The Case of the Vanishing Blonde":

After a woman living in a hotel in Florida was raped, viciously beaten, and left for dead near the Everglades in 2005, the police investigation quickly went cold. But when the victim sued the Airport Regency, the hotel’s private detective, Ken Brennan, became obsessed with the case: how had the 21-year-old blonde disappeared from her room, unseen by security cameras? The author follows Brennan’s trail as the P.I. worked a chilling hunch that would lead him to other states, other crimes, and a man nobody else suspected.

Now Bowden has written about Brennan again in "The Body in Room 348":

The hotel was just off the cloverleaf outside Beaumont. His company rented him a room in the “cabana,” a three-story wing that wrapped around a small swimming pool framed by potted palms.

That Wednesday night, watching his movie, Greg got an e-mail from his wife, Susie, shortly after seven. Susie was using a computer program to file for a tax extension. After she reported her progress he wrote back, “You’re doin’ good, babe.”

At some point during the loud, computer-generated showdown at the end of the film, amid all the fake violence, Greg was struck from nowhere with a very real and shattering blow. A blow so violent it would blind a man with pain. He managed to get off the bed and move toward the door before he fell, legs splayed and face-first.

He was probably dead by the time his face hit the green rug.

This is some amazing detective work, and it happened in real life. How long before we have a new TV show based on the exploits of Brennan? These are far more compelling stories than the "mysteries of the week" scripts of so many forensic TV shows.
