A judge has ordered tests to determine whether a former doctor convicted of killing four people connected to an Omaha medical school is competent to face a death penalty hearing.

Anthony Garcia sat silent in court Monday at a hearing to determine his competency. Judge Gary Randall warned Garcia that if he didn't answer questions, he'd be sent to the state psychiatric hospital for testing. Garcia remained mum, so Randall ordered him to the hospital.

In October, Garcia was convicted of killing the 11-year-old son and a housekeeper of Creighton University faculty member William Hunter in 2008 and killing pathology doctor Roger Brumback and his wife in 2013.

Prosecutors say Garcia blamed Hunter and Brumback for his firing 15 years ago from Creighton's pathology residency program.
