A Wayland man has been convicted of killing his ex-girlfriend a month after they graduated from high school.

Nathaniel Fujita (foo-JEE'-tuh) was found guilty Thursday of first-degree murder in the July 2011 death of Lauren Astley. They were both 18 at the time.

Fujita hung his head as the jury foreman read the verdict.

Astley's mother broke down in tears.

Prosecutors said Fujita was angry because Astley had broken up with him. They said he stabbed and strangled Astley, then left her body in a marsh.

A forensic psychiatrist testifying for the defense said Fujita lacked the ability to know his actions were wrong due to depression, daily marijuana use and repeated brain injuries suffered playing football.

A psychiatrist for the prosecution said Fujita acted out of rage and understood his actions.
