Police investigating the murder of Natalie McNally have been searching the grounds of Silverwood Golf Club in Lurgan.
Detectives have also visited business properties in Armagh and Craigavon to carry out enquiries as part of their investigation.
The 32-year-old was 15 weeks pregnant when she was stabbed on 18 December.
The council-owned golf club grounds are beside Ms McNally’s Silverwood Green home.
BBC reporter Kevin Sharkey said it was understood that the searches were not intelligence based.
He said much of the police focus was around pathways and shrubbery and it is understood the search was part of ongoing investigations which include an examination of potential off-road routes close to the scene of the murder.
Detectives attended a business property in Armagh and Craigavon yesterday to carry out enquiries as part of the investigation. They said there had been no searches in Belfast relating to the case.
Two arrests have been made in connection with Ms McNally’s murder but no-one has been charged.
Murder weapon
On Thursday police said they believed they had recovered the weapon used in her murder and that it came from her home.
Investigating officers believe she knew her killer, that they had a pre-existing relationship and that she was comfortable allowing him into her home.
Police also believe it was a targeted attack towards Mrs McNally.
Det Ch Insp Neil McGuinness said he was “keeping an open mind” as to whether it was a planned attack or something that developed when the killer arrived at Ms McNally’s home.
“I don’t believe Natalie’s door was locked,” he added.
“I believe the killer entered her home as soon as he walked up to her door.”
Former SDLP assembly member Dolores Kelly met the McNally family on Friday.
“The community is reeling, it really is. There’s a sense of shock and despair about what has happened,” Ms Kelly said.
She said the family were “desperately seeking answers”.
Alliance MLA Andrew Muir was formerly a colleague of Ms McNally’s at Translink, where she worked in marketing.
“It was a great privilege to work alongside Natalie,” Mr Muir told BBC News NI’s Newsline programme.
He described her as “a very kind, caring, conscientious person, someone who was very inclusive, a really strong advocate for equality”, and urged people with any information regarding her murder to come forward.
A silent vigil took place at Stormont for Ms McNally on Thursday afternoon.
Her brother Declan thanked the community for their support.
“Whatever differences of opinions there are in this country we know there is no difference of opinion and everybody wants to see an end to violence against women and girls,” he said.
Dad’s appeal to killer
“Everybody in society has to redouble our efforts to end violence against women and girls in memory of our sister Natalie.”
Her father Noel also made an appeal for his daughter’s killer to “find it in his heart to give himself up to the police”.
A 32-year-old man arrested on Monday 19 December was released the next day and is no longer a suspect.
Another 32-year-old man was arrested on Wednesday 21 December and has been released on police bail while detectives continue their inquiries.
The charity Crimestoppers has offered a £20,000 reward.
