Inmate’s execution is the 5th this year in U.S.

A Missouri man who killed a couple during a robbery at their rural home more than a quarter of a century ago was put to death Tuesday, becoming just the fifth person executed in the United States this year.

Carman Deck, 56, died by injection at the state prison in Bonne Terre. He was pronounced dead at 6:10 p.m. His fate was sealed a day earlier when neither the U.S. Supreme Court nor Republican Gov. Mike Parson stepped in to halt the execution. He was convicted of robbing James and Zelma Long of money and jewelry before shooting them to death in 1996 at their home in De Soto, about 45 miles southwest of St. Louis.

Just four other people have been executed in the U.S. in 2022 — Donald Anthony Grant and Gilbert Ray Postelle in Oklahoma, Matthew Reeves in Alabama and Carl Wayne Buntion last month in Texas. Eleven people were executed in the U.S. last year, the fewest since 1988.

The number of executions in the U.S. has declined significantly since peaking at 98 in 1998. The drop has coincided with a decline in public support for capital punishment that has fallen from a high of 80% in 1994 to 54% in 2021, according to Gallup polls. Since the mid-1990s, opposition to capital punishment has risen from under 20% to about 45%.

Use of the death penalty has become concentrated mostly in a few Southern and Plains states. Last year, Texas executed three inmates, Oklahoma executed two, and one each were put to death in Alabama, Mississippi and Missouri. Three federal inmates were executed in January 2021, toward the end of President Donald Trump’s administration.
