The former student accused of last week's deadly shooting rampage at a Florida high school returned to court on Monday for a status hearing.
The judge ordered that a defence motion filed last week remain sealed from public view.
Nikolas Cruz, wearing a red, jail-issued uniform, sat during the short hearing in Fort Lauderdale without showing any emotion, his head bowed.
The content of the motion filed by his lawyers was not described in the hearing.
Cruz is facing 17 counts of premeditated murder after the attack last Wednesday at Marjory Stoneman Douglas High School in Parkland, near Fort Lauderdale.
It is the deadliest shooting ever at a U.S. high school.
