The police watchdog has launched an investigation after an officer conducted a welfare check at Nicola Bulley's family home days before she went missing.
The Independent Office for Police Conduct (IOPC) said it was notified that an officer from Lancashire Police visited the address on January 10.
Ms Bulley's body was pulled from the River Wyre in Lancashire on Sunday, more than three weeks after she was last seen on January 27.
An inquest opening heard how the 45-year-old mother-of-two was identified by her dental records.
Confirming it had launched an investigation, a spokesman for the IOPC said: "Following a referral by Lancashire Constabulary on Thursday, we have started an independent investigation regarding contact the force had with Nicola Bulley on January 10 2023.
"We were notified by the force that an officer attended the family home on that date as part of a welfare check."
