The US state of Texas is likely to have executed an innocent man due to careless handling of the case, a report by US law students claims.
Carlos de Luna was killed by lethal injection in 1989 for the brutal murder of a single mother six years earlier.
Right up until his execution, de Luna maintained a fellow Hispanic called Carlos Hernandez was the real culprit.
The Columbia University report backs his claim. It says “shoddy police work” probably led to the wrong man dying.
