Two people have been arrested in connection with the fatal stabbing of a Japanese American man in Tustin, Calif. The city’s police arrested 19-year-old Miguel Orellana and 25-year-old Erika Pineda Dec. 28 on suspicion of murder, CBSLA reported.

David Nakaki, a 62-year-old resident of Tustin, was attacked at about 8:45 p.m. Dec. 9, and left for dead in the southbound lanes of Prospect Avenue near Norwood Park Place, according to Tustin Police Lt. Andrew Birozy, the Nichi Bei Weekly previously reported.

Motorist Pisith Hem had been riding in a car with his cousin when they saw Nakaki lying in the street, The Associated Press reported. They stopped the car and helped Nakaki, who was lying on the ground near the curb with his face to the pavement, bleeding out of his mouth. Hem called 911, but Nakaki succumbed to his injuries at a local hospital.

Police attributed the arrests to DNA evidence, witness statements and investigative work, CBSLA reported. Detectives said robbery was the apparent motive, the news outlet said.
