PORT ST. LUCIE, FL (WFLX) - Seventeen-year-old Tyler Hadley remains on suicide watch at the St. Lucie County Jail accused of murdering his own parents with a hammer. A key witness says Hadley was high on ecstasy at the time.
"I really don't see any motives besides drugs," said Mike Mandell, Tyler's best friend.
Mike is still trying to cope. He says he'll never forget what he saw in Hadley's Port St. Lucie home Saturday night.
His best friend's parents -- dead.
Mike says his best friend, Tyler, admitted to getting high before beating Mary Jo and Blake Hadley to death with a hammer. "He was on ecstasy." Three tablets of ecstasy said Mike.
Medical experts say that's enough "e" to make someone feel like they're "losing their mind".
Dr. Scott McFarland, Emergency Room Director at Palm Beach Gardens Medical Center, said, "They initially ascend this stairway to heaven and then descending into hell."
Dr. McFarland says that much 'e' drastically increases serotonin levels in the brain. "Agitated, confused, sweating, can have a fever. They can have seizures."
Mike told investigators about Tyler's demeanor, and police noted it, too.
In their report writing, "Tyler appeared nervous, frantic and very talkative while speaking to the officers. He also appeared to have a blank stare, and his pupils were very large."
"They have dilated pupils," said Dr. McFarland. "They are constantly in motion because it gives you the sense you have to move."
Dr. McFarland says taking "e" can cause hallucinations and creates a lack of inhibition in some people which, he says, can lead to potentially dangerous decisions. "You have no control over your sensorium, and you are a danger to yourself and others."
Police reports mirrored that possibility stating: "MM [Mike Mandell] also stated the defendant told MM that he was intending to kill himself by taking 10 Percocet pills when law enforcement officers eventually came to his residence."
Investigators continue to gather clues for prosecutors to build a case against him.
Funeral arrangements for Hadley's parents have come together. A service is planned for Saturday morning at St. Lucie Catholic Church.
