PORT ST. LUCIE, FLA. -- New details are emerging in the investigation into the bludgeoning deaths of Blake and Mary Jo Hadley.
Their son Tyler is accused of killing the pair with a hammer last July.
250 pages of information about the case reveal what allegedly happened in the days leading up to the Hadleys deaths.
Investigators say Tyler killed his parents with a hammer and held a party with friends while their bodies were inside the house.
Prior to that they say Tyler's friend Mike Mandell told them that Tyler had claimed to have stolen $11,000 and a credit card from his parents.
When arrested, the documents say Tyler was carrying more than $250 in cash, and his father's credit card.
While friends and family say Tyler seemed angry and suicidal at times, they described him as a typical teenager.
During a family vacation before the murders his family says his parents allegedly discovered Tyler purging.
Mandell also told investigators that after confessing to the murders, Tyler "showed no remorse, no regret, nothing."
According to the documents, Mandell said Tyler told him after the murders that he took a shower then looked in the mirror and laughed.
Mandell also told investigators that while Tyler had thrown a party in the home with his parents' bodies inside, Tyler may have been planning a "second" party.
The documents also reveal that Hadley admits to hearing a female voice inside his head.
