And in Texas, 59-year-old Ernest Willis walked out of prison yesterday after spending nearly one-third of his life on death row. He was convicted in 1986 of setting fire to a building that killed two sleeping women. During his trial, prosecutors described Willis to jurors as a “satanic demon.” But now the county’s district attorney is saying that Willis is not only innocent but that no crime may have ever been committed. There are strong indications the fire was an accident.
