A 70-year-old Waipahu farm worker who died when a truck backed into him at Aloun Farms last Saturday was identified  by a family member as Pedro Cervantes.

The Honolulu Medical Examiner’s office said Cervantes died of multiple internal injuries from the accident.

Cervantes was hit about 1 p.m. on a dirt road across from the Waipio Costco on Ka Uka Boulevard.

“I knew him as a good person,” said Monica Cablay, 18, a distant relative of Cervantes. She said he would visit her house on special occasions and left behind children and grandchildren. “He just looked like a happy person.”

Police have opened a third-degree negligent homicide investigation. The state Department of Labor and Industrial Relations is investigating the death.
