Yeah. But in this case it would be the ABSENCE of a paper trail that would be news.
Hmmmm, I wonder if reporting that such-and-such a doctor or hospital does NOT have a record of a particular patient would violate HIPPA rules?...
Along the same train of thought, reporting that such and such a person NEVER even registered at a certain hospital may not involve violation.
Back in 1961, I do believe women stayed in hospital for much longer periods than today after a birth delivery.
Another thought, follow the money. Was she under 18 and used her mom’s insurance coverage to pay for the delivery? Or was it a county deal? Insurance company rules/laws may apply differently.
For instance, if you were late for a dinner date, and you date called up all the local hospital to inquire whether you (your name) was in the system from a car wreck, the nursing supervisor is allowed to tell you yes or no, even a bit more.
Likewise, if a reporter called up the hospitals asking for summary of a person's status regarding a "newsworthy" case then release of general info is also allowed.
