Police now think the deaths of a mother and child found floating in the harbour may be a tragic case of murder-suicide.
According to sources close to the investigation, new evidence suggests Amanda Seymour Burrows, 32, was depressed at the time of her death. Based on this, officers think it is possible she murdered her daughter and killed herself.
Among this evidence is said to be a letter Ms Burrows wrote to herself detailing her troubles.
