A federal agent has testified that he's been told that there was someone else in the van with a woman accused of slamming into a school bus near Cottonwood last February, killing four children. The testimony came out in a pre-trial hearing in the case of Olga Franco, who's charged with criminal vehicular homicide among other things. Agent Jeremy Christenson with Immigration Customs and Enforecent testified that while conducting interviews as part of the crash investigation, someone told him Franco's boyfriend was with her at the time of the crash. The defense's contention is that the boyfriend, who apparently has fled to Mexico, was behind the wheel at the time of the crash.
