Despite having confessed to authorities shortly after
the December 1989 crimes, Robert Lookingbill, 37, maintained his
innocence in a recent newspaper interview.
Nevertheless, he said he was resigned to die. "When
it comes, you can't run from it and I'm not going to run," Lookingbill
said in a final statement from the gurney.
Lookingbill was convicted of beating his 70-year-old
grandmother, Adeline Dannenberg, with a steel bar as she slept in her
San Juan home. She died 10 days later.
The grandfather, 77-year-old Lorenz Dannenberg, was
beaten in the living room and died after a year in a coma. Lookingbill
was convicted of attempted murder in that attack.
The Supreme Court denied two requests for stays.
Lookingbill lived with his grandparents after serving
a prison term for burglary. He was 24 at the time of the crimes.
He was the third convicted killer put to death this
year in Texas.
