Attorneys for Rene Zarate have filed a motion for a new trial this week at the Buena Vista County Courthouse.
Zarate, 17, of Storm Lake was found guilty by a Buena Vista County jury last month in the 1999 stabbing death of Jorge Ramos, 47, of Storm Lake.
A hearing on the new trial motion is scheduled for Tuesday, March 6. Zarate's sentencing, which was set for March 5, has been continued.
Following Zarate's trial last month, defense attorney Matthew Sheeley of Des Moines indicated that Zarate would seek a change of venue along with the motion for a new trial.
Zarate was found guilty of first-degree murder, which carries a life sentence without parole.
