AUSTIN, Texas, Jan 29 (Reuters) - Texas is set to execute  Kimberly McCarthy by lethal injection  on Tuesday, the first  woman to be put to death in the United States in more than two  years.
The execution is scheduled to be carried out at the state  prison in Huntsville, Texas after 6 p.m. local time.
Women are rarely executed in the United States. Only 12  female inmates were put to death since capital punishment was  reinstated by the Supreme Court in 1976, according to the Death  Penalty Information Center.
The last woman executed was Teresa Lewis in Virginia on  Sept. 23, 2010, the information center said.
"Although women commit about 10 percent of murders, capital  cases also require some aggravating factor like rape, robbery,  or physical abuse," said Richard Dieter, executive director of  the information center, adding that women usually have not  committed a long list of prior felonies.
"It's unclear whether jurors or prosecutors may be more  lenient in potential prosecutions of women, since there are  relatively few," said Dieter.
McCarthy, 51, was convicted of entering the Lancaster, Texas  home of her 71-year-old neighbor, Dorothy Booth, on July 21,  1997, under the pretense of borrowing some sugar. She then  stabbed Booth five times, according to the Texas attorney  general's summary of the case.
She also cut off Booth's left ring finger in order to take  her diamond ring, which she later pawned.
McCarthy also was believed to be responsible for the murders  of two other elderly women, one using a meat tenderizer as a  weapon and another using a claw hammer, according to the  Attorney General's summary.
McCarthy was found guilty in 1998 by a Dallas County jury of  murdering Booth and sentenced to death. Her conviction was  overturned by the Texas Court of Criminal Appeals in 2001  because no attorney was present when she was questioned after  the crime even though she had requested a lawyer, court  documents show. She was tried a second time in 2002, was again  found guilty by a Dallas County jury, and again sentenced to  death.
The Texas Court of Criminal Appeals in 2004 agreed with the  second conviction.
McCarthy would be the second person executed in the United  States so far this year. Forty-three inmates were put to death  in 2012.     (Reporting by Corrie MacLaggan; Writing by Greg McCune)
