Tyler Hadley of Port St. Lucie, Fla. is charged with twin counts of first-degree murder in the deaths, which authorities say happened Saturday (7/16/11). He is being held without bond at a juvenile detention center.
The parents – Blake and Mary-Jo Hadley – were believed to have been struck with the hammer in their heads and torsos sometime after their son posted on Facebook around 1:15 p.m. Saturday alerting friends to an evening party at his house.
Investigators believe the parents were attacked outside their master bedroom and the bodies were moved into the bedroom and the door locked.
As many as 60 people attended the party that night, according to Port St. Lucie Police.
