Albuquerque, NM - Today, Attorney General Hector Balderas announced that the Supreme Court of New Mexico agreed with the Office of the Attorney General's Criminal Appeals Division and affirmed Carlos Carrillo's convictions for the 2011 murders of Christopher Kinney and Lyndsey Frost. The victims were found shot to death in their truck near Tiguex Park in Albuquerque. The Supreme Court affirmed the admission of testimony from an employee of Cricket showing a record of 83 cell phone calls between the defendant and Kinney in the hours before the shooting and evidence showing the location of every cell phone tower in Albuquerque. The Court also held that testimony regarding how cell towers operate and interact with cell signals to locate the origin of a cell phone call is scientific or technical evidence that requires expert testimony. Finally, the Court held that there was sufficient evidence to support the murder convictions.
