White is set to become the sixth man executed in the U.S. in an 11-day period and the fifth inmate put to death in Texas so far this year.

Garcia Glenn White apologized for the pain he had caused and said he hoped his victims' families could now find peace in his final words before his execution.

A Texas man linked to five killings and convicted of fatally stabbing twin 16-year-old girls more than three decades ago is facing execution on Tuesday evening. Garcia White was condemned for the December 1989 killings of Annette and Bernette Edwards.
