Jasmine Fiore -- Ex-BF & BFF Fell in Love After Grisly Murder

One was Jasmine Fiore's ex-boyfriend, the other was her good gal pal -- and now, the two are getting married ... just over two years after the model was brutally murdered and stuffed into a suitcase.

Their names are Robert Hasman and Lacey Lemak -- and while it's unclear how or when they met, Jasmine's murder clearly brought them closer together ... because Robert proposed to Lacey not long after the horrific incident.

You may recall ... Robert infamously spoke out against Jasmine's alleged murderer Ryan Jenkins -- claiming he was glad the guy hanged himself.
