With abortion a hot-button issue in Ireland, there has been political fallout from the controversy, too.
Prime Minister Enda Kenny is under pressure to get Halappanavar to assist with a Health Service Executive inquiry into his wife's death, which was the first investigation set up.
But Halappanavar says government steps so far have done little to inspire confidence, not just because officials took weeks to announce the inquiry, but also because when they did, three of the seven medical professionals on the investigation team were from the same hospital where his wife died.
Although they have now been replaced on the team, other issues remain, Halappanavar said.
"We made a request for termination and there is no note of the request at all, and of the medical notes. The response from the doctor is not in the medical records either."
Asked what he thinks has happened to the information, Halappanavar has no answer.
"We don't know what has happened to it," Halappanavar said. "It is strange that all other information is in there -- when we requested things like tea and toast, and when things like we requested an extra blanket, all that is in the medical notes."
Halappanavar says he will settle for nothing less than a full public inquiry -- one in which the wider health service, not just his wife's death, is investigated by independent experts.
"Every single person in the family asked me how could this happen in a place like Ireland in the 21st century, because it was just so simple," he said.
"When they knew the baby was not going to survive, why not think about the bigger life which was the mother, my wife Savita? And they didn't."
All he wants, he said, is the truth.
