  Port St. Lucie Police crime scene investigator Jeanine Hickox talks with a police officer at a crime scene in Port St. Lucie on Monday, July 18, 2011. A Florida teen is accused of posting a Facebook invite for a house party, killing his parents with a hammer and then hosting dozens of people while the adults' bludgeoned bodies were locked in the master bedroom. Tyler Hadley, 17, was expected to make his first court appearance Tuesday. He is charged with two counts of first-degree murder in the deaths of Blake and Mary-Jo Hadley, who police believe were struck on their heads and torsos on Saturday, sometime after their son posted on Facebook to tell friends about the party. Investigators believe the Hadleys were attacked outside their master bedroom and the bodies were moved into the bedroom and the door locked. (AP Photo/The Stuart News, Deborah Silver)
