A former South Dakota prosecutor has been arrested in connection with a killing in Tempe.
Dan Gukeisen was jailed after a 22-year-old Arizona State University student was stabbed to death Friday on a downtown Tempe street.
The 37-year-old Gukeisen has not been formally charged.
Gukeisen was a deputy state's attorney in Lawrence County for about three years, and he also served for a year as Davison County state's attorney.
He currently works as a bankruptcy attorney in Phoenix.
Tempe police say the victim, Garrett Hohn, got into an argument with Gukeisen and was stabbed.
