Shelar said his wife was upset about a recent ultrasound.
"On November 15 we went for an ultrasound test at the hospital. She had always dreamed for a baby boy but that day after the ultrasound they were not sure if it was a girl or boy.
"As soon as we got in the car she was crying and so upset because she wanted a boy," he said.
Detective Senior Sergeant Warwick McKee of Wellington CIB today said they had increased the size of the team searching for Shelar.
