POLICE investigating the death of three babies were using sniffer dogs today to search the garden of a third property involved in the murder inquiry.
South Wales Police detectives had until lunchtime to question grandmother Ann Mahoney, 64, held on suspicion of murder, after they were given an extra 36 hours to detain her on Wednesday night.
Detectives can choose to request a further 24-hour custody extension, bring charges, or release her.
She was arrested at her home in Forsythia Close, on the Gurnos estate in Merthyr Tydfil, on Tuesday.
Her arrest was originally linked to the discovery of a baby's body in a suitcase in the attic of a house in nearby Penyfan View on March 20.
Then police announced they had discovered the suspected remains of two other babies following a search at her current address on Tuesday.
Now shocked residents on the Gurnos estate are facing a second day of police searches at a third property.
A specialist police team arrived at the Crabapple Close property yesterday where uniformed officers had been keeping guard.
It is understood that bore holes will be dug in the property's garden today after the grass was cut back yesterday.
Special sniffer dogs trained to locate human remains will then be used to criss-cross the ground in an effort to locate any potential human remains.
Sniffer dogs were used to search inside the council house yesterday.
The house, which is rented to a tenant, belongs to Merthyr Tydfil Council, but was previously home to the pensioner.
