Teenage addicts have turned a talented musician's Bradford home into a drug den since her death five years ago, according to her neighbours.
Mystery surrounds the ownership of the East Bowling terraced house which remained relatively untouched when 94-year-old Florence Dunn died.
That was until yobs began breaking in to use it as a hangout.
Residents who have been inside say her belongings, which included a piano and electric organ, have been destroyed, and that the floor is littered with syringes from drug abuse.
They also claim the house in Stafford Street has become a health hazard and is plagued by mice and damp.
Next-door neighbour Keith Mudd, 36, lives in fear of the youngsters causing a fire.
He said: "There are people coming and going at all hours of the night and quite often they play loud music.
"I have seen lighted candles after dark and I come home expecting to find it up in flames."
Miss Dunn grew up in the house as an only child and spent the twilight years of her life living there alone.
It is believed she did not leave a will, and the Land Registry says it has no record of its owner because the house has not changed hands since its records began in 1974.
Neighbour Iris Wagstaff said her partner has made repeated attempts to seal the house, but youths keep kicking the back door open to get in.
"This is an insult to her memory," she said. "She was a talented musician who would shut herself away and play classical music.
"Inside the house there are all sorts of personal things. I think a relative moved items such as cash and documents, but it looks as if everything else is still there."
Rupert Oliver, of the East Bowling Regeneration Organisation, added: "The house has become a magnet for trouble - something must be done about it."
PC Mick Fawbert, community beat officer for East Bowling and Bierley, said he had made contact with a relative of Miss Dunn's who believes she has a claim to the property.
Bradford Council is also attempting to discover who owns the property.
PC Fawbert said: "It is unfortunate that properties are left in such a state of decay because they will become a target for crime.
"All necessary steps will be taken to establish the owner in order that the problem can be rectified."
A Bradford Council spokesman said: "An officer will visit to assess the situation and we will then take appropriate action such as securing the house.
