The deaths of three graffiti artists is a tragedy for their friends and families (Lethal tags: London’s perilous places hold spray painters in thrall, 23 June), but we should also spare a thought for the train drivers who will be asking themselves “Was it my train that killed those three young men?” When a person dies after being hit by a train, the train driver may suffer years of mental anguish.

• “Officers originally thought Palmer had died of natural causes because of recent keyhole surgery to his chest, but it later emerged that he had been shot six times at close range” (Family of rich criminal offers £100,000 for leads to catch murderers, 22 June).

• I loved my Morris Traveller (Letters, 23 June) because, even as a mechanically illiterate young woman, I could always fix its only two faults. If the fuel pump stopped working, I thumped it; and if the exhaust fell off, I tied it back on with string. Even the most minor problems with any subsequent cars have meant costly trips to the garage.
