The penalty trial of Florida school shooter Nikolas Cruz will be delayed until April after prosecutors told the judge Wednesday that they needed more time to interview the mental health experts who are expected to testify on his behalf.

Circuit Judge Elizabeth Scherer reluctantly moved the start of jury selection from Feb. 21 until the first week of April after attorneys for both sides conferred behind closed doors. That will be almost four years and two months after the Feb. 14, 2018, shooting at Marjory Stoneman Douglas High School in Parkland that left 14 students and three staff members dead and 17 wounded.
