A federal judge today ordered a competency evaluation for the driver in a rollover accident that killed four illegal immigrants last fall.

Jose Francisco Franco-Rodriguez was at the wheel of a 1998 Dodge Caravan that went off an icy I-70 near Idaho Springs on Nov. 28. In addition to the dead, 10 others were in the vehicle.

At the request of Franco-Rodriguez's attorney, Judge Marcia Krieger ordered an evaluation of whether the defendant is competent to stand trial. The process is expected to take six to eight weeks.

Franco-Rodriguez is charged with transporting aliens resulting in death and re-entering the United States after he was deported.

He faces life in prison.
