FORT PIERCE — Evidence filed Thursday afternoon by the State Attorney's Office indicates that Tyler Hadley hinted to several friends during a party at his family home July 16 that he had killed his parents earlier in the day.
Tyler Hadley, 17, told two friends he would be going to prison for a long time, adding to one it was because he "did something bad."
Tyler Hadley is charged with two counts of second-degree murder for the bludgeoning death of Mary Jo Hadley, 47, and Blake Hadley, 54, both of Port St. Lucie.
Authorities allege Tyler Hadley posted invitations to a party at the family home on Facebook on the afternoon of July 16, beat both his parents to death with a hammer soon afterward and hosted about 60 partygoers at the house in the 300 block of Northeast Granduer Avenue that night.
A previously released affidavit from a teenager who told Port St. Lucie Police he was Tyler Hadley's best friend details how Tyler Hadley claimed he stood behind his mother about five minutes as she sat at the computer, thinking about killing her before striking the fatal blows.
The friend told police Tyler Hadley said his father came into the room and the two looked at each other before Tyler Hadley began striking his father with the hammer.
Paperwork filed Thursday shows police interviewed about 20 other people who attended the party at the Hadley home.
According to synopses of the witness statements, Tyler Hadley told friends during the party:
"Dude, something crazy is going to happen in the next week."
He was going away for a while "if I don't kill myself before I go." When the friend said, "Then don't go," he replied: "It ain't that simple. ... You're my boy; let's hang out again soon."
His father had passed away.
His father at one time had hit him after an argument.
His parents didn't live at the house where the party was taking place; it was his house.
He was going to prison for 60 years because he "did something bad" and that he would rather die than go to prison.
When asked where his parents were, the friend said, Tyler Hadley did not respond.
Tyler Hadley was scheduled to be arraigned Friday morning but has waived the appearance before Circuit Judge Dan Vaughn. The 19th Circuit Court Public Defender's Office has entered a written not-guilty plea on his behalf.
The State Attorney's Office is expected to convene a grand jury on the case later this month. An indictment is needed to upgrade the second-degree murder charges to first-degree murder.
A spokesperson for the Port St. Lucie police department has stated that even though the crime scene tape is down, and authorities have cleared the scene, this investigation is far from over.
