Mental health experts were expected to begin testifying Wednesday in their insanity defense for 17-year-old Treacy.

The defense claims Treacy suffered from post-traumatic stress disorder when he assaulted Josie Lou Ratley outside a middle school in 2010. The disorder supposedly started after Treacy's brother committed suicide by hanging himself a few months earlier.

Now 17, Ratley almost died and suffered permanent brain injuries. The attack happened after the two exchanged taunting and insulting text messages, culminating with one from Ratley referring to Treacy's dead brother.

Ratley did not testify in the trial.

Treacy faces a possible 50-year prison sentence if convicted of attempted first-degree murder.
