Colleague's tribute to Florida gun victim James Cooper

US detectives are investigating how two British friends were shot dead on holiday in Florida, several miles from any recognised tourist area.

James Kouzaris from Northampton and James Cooper from Warwick had become friends while studying at Sheffield University.

Mr Cooper had worked as a tennis coach for inspire2coach at the University of Warwick.

The BBC's Giles Latcham spoke to the company's director, Mark Tennant, who said "everybody thought he was a great guy" with "a promising career ahead of him".
