A British man who was convicted of shooting dead his wife and nine-month-old daughter in 2006 has filed an appeal, arguing that he should get a new trial because police searched his US home without a warrant when they came to check on the well-being of his family.
Neil Entwistle was convicted in 2008 of the murder of his wife, Rachel, and baby daughter Lillian Rose in Massachusetts.
Prosecutors say Entwistle had become despondent after accumulating tens of thousands of dollars of debt and had complained about his sex life with his wife.
In a brief, Entwistle's lawyer argues that evidence taken from the home was seized illegally.
Prosecutors have said police were justified in entering the home because they were responding to the pleas of concerned relatives and friends.
