Deliberations begin in Wayland murder trial

WAYLAND, Mass. (WHDH) -- Wednesday morning, the jury starts deliberating the case against a young man from Sudbury, accused of killing his ex-girlfriend.

That is after some emotional closing arguments on Tuesday.

“The evidence shows Lauren Astley had moved on. Nathaniel Fujita had not.

Lauren reached out in friendship, Nathaniel responded by killing her,” said prosecutor Lisa McGovern.

The prosecution re-enacted the way they say Fujita killed ex-girlfriend Lauren Astley.

Fujita's parents wept behind their son in court.

The defense told the jury that Fujita was mentally ill.

"the defendant felt outside of his box...was unable to control what he was doing or even really understand what he was doing,” said defense attorney, William Sullivan.

Prosecutors say Fujita strangled and stabbed his 18-year-old ex-girlfriend.

If convicted, he faces life in prison without parole.
