Ms Telea was distraught when she heard the toddler had died. "He was such a happy baby."
Warehouse storeman Stefan Ruta also witnessed the aftermath of the tragedy. He was leaving his home nearby when he heard a "big bang" and "saw the ... father, running up the driveway. He was in really big shock. Another man jumped in the car and they went to the doctor's".
Police said the driver of the vehicle was helping them with their inquiries.
Mr Ruta said he knew both parents. They were about 18 and attended Sir Edmund Hillary College until last year. He believed the toddler was their only child. "I'm in shock ... I've got two little ones myself. I'm going to give them a big hug."
