A drone has been used to search the fields around the area where Anita Rose is thought to have been attacked in Brantham.
A murder investigation into the death of mother-of-six Ms Rose is ongoing after she was attacked in the village on Wednesday, July 24.
The 57-year-old was found by a member of the public lying on a track road near to Rectory Lane in Brantham, near to the sewage works and railway line, at about 6.25am.
On Tuesday, police were seen using a drone to gather aerial footage of the fields close to where she was found seriously injured.
The search follows police appeals for a pink jacket Ms Rose is known to have been wearing which has still not been recovered.
Initially her Apple iPhone was also missing - but police say they have located and found that.
There has been a heavy police presence around the scene of the attack since police were first made aware of it.
Officers dressed in black have been seen conducting sweeps of the surrounding countryside to build a clearer picture of what happened and find the missing jacket.
The police recently released a map of where Ms Rose is said to have walked before she received a serious head injury and was left in a critical condition.
Previously in the investigation at about 1pm on Saturday, Suffolk police officers arrested a 45-year-old man from the Ipswich area on suspicion of attempted murder.
He was subsequently re-arrested on suspicion of murder.
A 37-year-old woman, also from the Ipswich area, was also arrested on Saturday on suspicion of handling stolen goods in connection with the incident.
The pair were taken to Martlesham Police Investigation Centre for questioning, and have been released on bail with conditions to return on October 25.
Detective Superintendent Mike Brown previously said: “We are keen to speak to anyone who saw anything on Wednesday in the areas shown on the map or anyone travelling on trains towards Ipswich or Manningtree on that morning that saw anything that they think could be of use to the investigation.”
