A surgeon pushed his ex-wife off a cliff and for the following seven months updated her social media in a sophisticated ploy to avoid suspicion of murder, police say.
Dr Dharmendra Pratap Singh has now been arrested in connection with Rakhi Srivastava's death after allegedly sedating her.
She went missing in June, not long after remarrying following her split with Singh.
And. cops say Singh regularly changed Ms Srivastava's Facebook on her phone in the months since in an attempt to fool them.
Ms Srivastava's social media was also allegedly updated after her death
But her phone was found in October.
"This made Dr Singh a prime suspect," a police source said.
"However, even after killing Rakhi, they kept updating her social media account through her mobile phone."
Ms Srivastava's family has made an emotional plea for more information.
The investigation continues.
