Officers have completed their search of paedophile Norman Duncan's former home in Bonhill.
Police Scotland confirmed they finished their search of the Ladyton house on Tuesday this week.
The Lennox Herald exclusively revealed how cops swooped on the property as part of their probe into the disappearance of 17-year-old Mary Duncan, who went missing 43 years ago and is the stepdaughter of Norman Duncan.
The 73-year-old is currently serving five years for sex offences against young girls between 1968 and 1976 and lived at the Ladyton before he was jailed in 2016.
Police previously confirmed they had spoken to Duncan in relation to the inquiry.
A forensic team spent seven days at the terraced house after beginning to comb through the property on Wednesday last week.

This week, Mary's sisters told how they are praying for some closure at last.
Mandy Duncan said she and her two siblings are sitting by the phone hoping for a breakthrough in the investigation .
She said: “We are praying that there is something in that house which will lead us to Mary and bring us closure. All we can do now is wait — we just want it to be over.”
Mandy’s beloved sister went missing aged 17 from her home in Third Avenue, Bonhill, on March 19, 1976.
No trace of the young mum has been found despite an extensive investigation.
A police spokeswoman said: "A search of a house in Ladyton has now been completed.
