A 16-year-old boy has been arrested on suspicion of murder following an incident in Carmarthenshire.
Officers were called to a property in the St Clears area at about 17:40 GMT on Tuesday.
A Dyfed-Powys Police spokesman said the force was investigating the murder of a woman and the teenager was in custody.
The woman has been named locally as Fiona Scourfield, also known as “Suzi Wales” who was a member of German Shepherd Rescue UK.
St Clears mayor Jane Rees described the incident as “shocking”.
