The Houston Chronicle researched the execution of Ruben Cantu who was executed in 1993. Their conclusion is that he was innocent of the murder.
There was only one eyewitnesses and no physical evidence. The witness has recanted:
When the crime was first investigated, there were no strong suspects. Moreno did not identify Cantu. Later, Cantu shot a police officer (he admitted it) but the investigation was too shoddy to prosecute. So the police decide to get him for the previous murderer. They showed Cantu's photo to Moreno again. He said it was not the murderer. Finally, the third time, Moreno said Cantu was the murderer:

There was only one eyewitnesses and no physical evidence. The witness has recanted:
And the lone eyewitness, the man who survived the shooting, has recanted. He told the Chronicle he's sure that the person who shot him was not Cantu, but he felt pressured by police to identify the boy as the killer. Juan Moreno, an illegal immigrant at the time of the shooting, said his damning in-court identification was based on his fear of authorities and police interest in Cantu.
Cantu "was innocent. It was a case of an innocent person being killed," Moreno said.

On the first round of appeals, even the Texas Court of Criminal Appeals ruled that the identification process was improperly suggestive, though the court upheld the in-trial identification and did not overturn Cantu's conviction. "In the abstract the process of showing Juan several arrays on different occasions, all containing the appellant's photograph is a suggestive procedure. Such procedure tends to highlight a particular defendant since the witness sees the same face repeatedly. Such reoccurrence of one particular face might suggest to the witness that the police think the defendant is the culprit," a February 1987 opinion read.
