I never found this out before
"When Buddy Holly died, his pregnant wife first got the news through the TV, and the shock caused her miscarriage, leading to the policy requiring families to be informed before media can release the victims’ names.
Holly’s pregnant wife, María Elena, watched the first reports of his death on television. A widow after six months of marriage, she miscarried the following day, attributed to “psychological trauma?.
Sucks that his child did not survive and interesting that it caused a major policy change.
