Middlesex Superior Court jurors are scheduled to begin deliberations Wednesday in the murder trial.

The 20-year-old Fujita is charged with strangling and stabbing Astley in July 2011. They were both 18 at the time.

Defense attorney William Sullivan said in closings Tuesday that his client had a psychotic episode at the time of the killing and wasn't responsible for his actions.

Assistant District Attorney Lisa McGovern said Fujita killed Astley "with deliberate premeditation," and the slaying was carefully planned. McGovern said there is no such thing as a "psychosis fairy."
