"Daniel Lewis Lee, 47, was injected with a lethal dose of pentobarbital at 8:07 a.m., just hours after the Supreme Court greenlit the first federal execution to take place since 2003."
Lee was convicted of multiple offenses, including three counts of murder in aid of racketeering in the 1996 slayings of William Frederick Mueller, his wife Nancy Ann Mueller and his 8-year-old stepdaughter, Sarah Elizabeth Powell.
