The judge asked Darren Vann, 43, of Gary, Indiana, if he swore to tell the truth and to also confirm his name at an initial court appearance in the strangulation death of 19-year-old Afrikka Hardy.
But Vann stood unmoving and stone-faced, staring back silently at the judge.
After a pause, Magistrate Judge Kathleen Sullivan warned Vann as he stood before her in striped jail garb and with his wrists and legs shackled that he would be held in contempt.
"Mr. Vann, are you choosing not to take part in this hearing?" Sullivan asked Vann during the hearing.
Sullivan then addressed Vann's public defender, Matthew Fech, urging him to advise his client speak.
"Tell your client that he stays in jail the rest of his life until this hearing takes place," she said.
Vann's public defender walked up to Vann and put his hand on his shoulder, encouraging him to speak. But he again offered no response.
The judge then found him in contempt and said she would schedule another initial hearing for next week.
Vann's lawyer finally convinced Vann to at least enter the room, he added.
Until this morning's hearing, the sheriff said Vann's demeanor had been "quiet, calm and collected," which included confessing to investigators and leading police to abandoned homes where several bodies were hidden.
Vann is already being held in isolation and is on 24-hour-a-day watch at the county jail, Bunich said, so it's unclear how the contempt charge will alter his status.
At the less than 10 minute hearing, the judge also issued a gag order, meaning investigators can no longer interview Vann unless they first get his permission through his attorney, Buncich said.
It's unclear if Vann will, in fact, stop speaking to authorities about the killings. His public defender did not comment after the hearing.
