Arizona Wednesday executed a death-row inmate convicted of killing a Tucson college student after robbing him of $200 — the state's third execution this year.

The death Wednesday of 63-year-old Thomas Arnold Kemp puts Arizona on pace to match its busiest year for executions and makes it one of the nation's busiest death-penalty states.

Kemp was sentenced to death for kidnapping 25-year-old Hector Soto Juarez from outside Juarez's Tucson apartment on July 11, 1992, and robbing him before taking him into the desert near Marana and shooting him twice in the head.
