The trial of a former Mazda Motor Corp. worker who went on a deadly driving rampage at the carmaker's plant complex in 2010 ended Friday, with prosecutors demanding life imprisonment and the defense seeking his acquitted on grounds of temporary insanity.

Toshiaki Hikiji, 44, is charged with murdering Hiroshi Hamada, 39, and with attempting to murder 11 other male employees he struck during his crazed car attack June 22, 2010.

The incident occurred in Hiroshima Prefecture at Mazda's adjoining auto plants in the city of Hiroshima and the town of Fuchu, two months after Hikiji had retired as a seasonal worker.
