The attorneys said Friday that Pagourtzis has yet to undergo a mental health evaluation, but the professional who will conduct that review has been selected.
Last week, Poehl told our sister station, ABC13 in Houston, that the suspect didn't remember much of what happened on May 18.
Pagourtzis remains in solitary confinement in Galveston County Jail, where he has been permitted to receive two 20-minute visits in jail each week.
