A fatal collision on the Tomei Expressway in June appears to have stemmed from road rage, as a man arrested by police confessed to losing his temper in an argument and subsequently chasing the victims' car, investigative sources said Thursday.
Kazuho Ishibashi, 25, was arrested Tuesday on suspicion of causing the June 5 accident in which Yoshihisa Hagiyama, 45, and his wife Yuka, 39, died on the expressway in Kanagawa Prefecture. Their two school-age daughters sustained minor injuries.
The Hagiyama family is from Shizuoka Prefecture.
