Texas executes its fifth person this year.

FOX's Carmen Roberts reports:

Twelve minutes after lethal drugs began flowing through 33-year-old Adam Ward Tuesday night, he took his last breath.

His attorneys had argued Ward should be spared from execution because he was delusional and mentally ill, but the U.S. Supreme Court rejected that last minute appeal.

Texas executed Ward for the 2005 shooting death of a city worker taking photos of piles of junk outside his home near Dallas. Ward said it was self-defense, but the victim, 44-year-old Michael Walker, only had a camera and a cellphone.

In his last few moments, Ward said he hoped, "some positive change can come from this."
