The trial for the man known online as "El Diablo" could be postponed indefinitely.
That's after it was decided on Thursday that Jacob Esparza is incompetent to stand trial.
Investigators say Esparza sent out several threats against West Texas officers and their families back in November.
A psychological evaluation determined Esparza suffers from a mental disorder.
Apparently, he was not taking his medications when he made the threats.
A tentative trial date has been set for April 16.
In the meantime, Esparza will be getting psychological help.
If the treatments don't work, the trial could be postponed indefinitely.
