Taxi driver Christopher Halliwell, 48, has been sentenced to life imprisonment after pleading guilty at Bristol Crown Court to murdering nightclubber Sian O'Callaghan. She disappeared after a night out in Swindon in March last year.
The Independent Police Complaints Commission (IPCC) is to investigate breaches of the Police and Criminal Evidence Act 1984 in the investigation into the deaths of Sian O'Callaghan and Rebecca Godden.
The three complaints that were upheld by the IPCC were not related to Detective Superintendent Steve Fulcher and are not subject to any misconduct proceedings.
The IPCC is to conduct a separate investigation into allegations that Detective Superintendent Steve Fulcher from Wiltshire Police spoke about the case to some media outlets against force instructions, the force media strategy and policies. He has been suspended pending the investigation.
The murder trial into the death of Sian O'Callaghan has ended, with the life imprisonment of her killer - taxi driver Christopher Halliwell.
Wiltshire Police have made a statement following the jailing for life of Christopher Halliwell for the murder of Sian O'Callaghan.
