Nearly a decade into his life sentence for murder, Lydell Grant was escorted out of a Texas prison in November with his hands held high, free on bail, all thanks to DNA re-examined by a software program.

or Grant, to get to here hinged on two necessary prongs: the DNA evidence, which was reanalyzed through an emerging software that has also come under scrutiny, and an unprecedented decision to use the findings to conduct an FBI criminal database search that was initiated by a third party not part of the initial investigation. That ultimately led to the discovery of a new suspect, who has been charged after police say he confessed.

The search process used in Grant's case has enormous potential to solve cold cases or re-evaluate other convictions that could pave the way for more exonerations nationwide, forensic scientists say.

"There's probably 5,000 or 6,000 innocent people in Texas prisons alone," said attorney Mike Ware, executive director of the Innocence Project of Texas, which is representing Grant. "How many of them could benefit from such a reanalysis of DNA that was used to convict them? I don't really know, but this is a historic case that could open the door for those who thought it was shut forever."

Investigators also interviewed seven witnesses, all but one of whom picked out Grant as the suspect from a photo lineup.

Jurors also heard from Grant's alibi, who said he was with him on the night Scheerhoorn was murdered, but his testimony failed to sway them, court documents show.
