Back in 1992, investigators had initially become suspicious when Robert Carter, the father of Jason Davis - the youngest victim - showed up at the funeral with his face and hand bandaged. The DPS Intelligence Unit had the funeral under surveillance and captured an image of the injured Carter sitting next to his wife, Theresa.

After the funeral, Texas Rangers went to see Robert Carter at his home. The Rangers had learned that Lisa Davis - victim Bobbie Davis' daughter - had recently filed a paternity suit against him for his now deceased child Jason. Carter was read his rights and brought in for questioning.

After hours of questioning, Robert Carter named this man - Anthony Graves - as his accomplice. Carter claimed he had been present, but that it was Graves - his wife's first cousin - who was to blame. Carter stumbled on Anthony's name a bit, calling him "Kenneth" at one point, but this did not seem to raise any red flags.

Later that day, Anthony Graves, 26, was picked up at his mother's home and brought to the Brenham Police Station where he was read his rights and told he was being charged with capital murder.

Anthony Graves' sister, Deitrich, was another alibi witness. She was also in the apartment with Anthony the night of the murders. Deitrich was never called by the defense to corroborate her brother's story.

Anthony Graves had an even more important alibi witness - someone not related to him: his girlfriend, Yolanda Mathis. But on the day she was to testify, she unexpectedly refused. Her absence would leave a gaping hole in Graves' defense. She later explained she had felt intimidated by the prosecution.

Roy Rueter's knife, shown here, was introduced in court as being identical to one that Anthony Graves had owned. Rueter reluctantly went on to testify against his friend after he was told by members of the D.A.'s office that the knife had fit into the skull wounds of two of the victims.

Burleson County D.A. Charles Sebesta was confident in his case and in Anthony Graves' guilt. As he points out, he not only had the knife evidence but the words of Robert Carter against Anthony. Carter later recanted and the knife evidence was refuted.
