You might mean the case of Florence Horner, kidnapped in 1948 by Frank La Salle. It’s apparently directly referenced in ‘Lolita’. However, Wikipedia mentions that Nabokov was already working on ‘Lolita’ in '47, under its original title ‘The Kingdom by the Sea’; and he had similar themes in previous works, going back to a poem and a novella from '28 and '39 respectively.
Importantly, ‘Lolita’ has a few brief allusions to Lewis Carroll, and multiple to Charlie Chaplin’s relationship with Lita Grey.
