THE word ‘tragedy’ is often misused.

But it does accurately describe exactly what happened to popular Sergio Marquez, who had his whole life ahead of him.

Yesterday at Bournemouth Crown Court his housemate Karl Addo admitted brutally killing him last summer.

Sergio’s brave mother Maria was there to hear the outcome after travelling over from Spain alongside friends and family.

And you would have to have a heart of stone not to be moved by her touching tribute to her beloved son, who she must miss greatly.
