An 88-year-old Florence man, Keith Smith, pleaded guilty yesterday to voluntary manslaughter in the 1967 death of Roxanne Marie Archuletta, a 14-month-old baby. Smith was sentenced to four years of supervised probation under a plea agreement. The case, ruled accidental at the time, was reopened in 2021 and sent to a grand jury. Family members expressed frustration, feeling the sentence does not bring justice for Roxanne.
