Executions Spread From South, Become Part of U.S. Landscape
By James Brooke
Two decades after US Supreme Court reinstated death penalty, states are executing prisoners at steadily accelerating pace, with executions spreading nationwide away from traditional Southern base; of 38 states that allow death penalty, 29 states have had executions since 1976, and executions are at 40-year high, with 59 people executed thus far in 1997; within past year Oregon and Kentucky carried out first executions since 1962, and by end of 1998, Connecticut, Ohio, Tennessee and New Jersey are expected to follow suit; nationwide, Texas has accounted for 138, or about 1 out of 3, inmates executed since 1976, followed by Virginia, Florida, Missouri, Louisiana, Georgia, Alabama and Arkansas, which together account for 337 of 417 executions; increase in executions attributed to new Federal laws curtailing appeals and financing for new defense lawyers; number of death row inmates nationwide has increased by almost 10 percent in past two years, to 3,269 in August; Colorado carries out its first execution in 30 years, putting Gary Davis, convicted rapist-murderer to death by lethal injection; photo (M)
