Four British tourists have been killed in Lanzarote in the Canary Islands when their fourwheel drive vehicle veered off a road and overturned. The victims were identified by the Civil Guard as Jason Maguirre, 31, Michael Anthony Maguirre, 27, Julie Johnson and Martin Cartey. The ages of Johnson and Cartey were not immediately released. The driver, Gary Hilton, 38, also a Briton, was reported to be in serious condition with a concussion in the Hospital Negrin of Gran Canaria. The tourists were travelling from Arrecife, the capital of Lanzarote, to Playa Blanca on the coast. The adoptive mother of Mr Cartey said she could not believe her son was dead. Patricia Mahoney, of the Ladbroke Grove area of west London, said: I have been told he is dead but I am still just hoping that he isn't. We have heard different reports from the local police over there and I just don't want to believe that Martin has died. Mrs Mahoney said Mr Cartey, an unemployed labourer, had travelled out to Lanzarote with the Maguire brothers last week. She said Ms Johnson was living in Lanzarote with her father but was originally from Britain. Mr Hilton was being treated at the Hospital Negrin in Gran Canaria, the spokeswoman added yesterday. Spanish police have launched a full investigation into the accident.
