Harshita Brella, 24, was found dead inside a Vauxhall Corsa in Ilford, east London, on 14 November last year, four days after she is suspected of having been strangled in Corby, Northamptonshire.
On 29 August, it was reported to Northamptonshire Police that she had suffered domestic abuse by her then husband Pankaj Lamba.
The suspect was arrested on 3 September and released on police bail, with conditions not to contact his wife, and issued with a Domestic Violence Protection Order.
A manhunt remains ongoing to locate Lamba who is believed to be in India after fleeing the UK.
The IOPC has now concluded its investigation into the actions of two detectives who were assigned to the domestic abuse investigation, plus two more senior officers who had supervisory responsibility, and found that two detective constables have a case to answer for gross misconduct.
The investigation also concluded there is a misconduct case to answer for a sergeant and chief inspector.
