For more than 40 years, police investigating the brutal murders of two women in Sydney's eastern suburbs believed it was likely the work of one killer.

Now the investigation into the killings of Lynette White and Maria Smith have been split up, after a detailed review revealed there was actually no definitive link between the crimes...

Maria Smith, 20, was found raped, gagged and bound inside her Randwick apartment on April 22, 1974.

The student teacher was strangled with her own stockings and left for her husband to find later that day.
