deciding whether 25-year-old antolin garcia-torres murdered sierra lamar. the prosecutor says garcia-torres' dna was found on sierra's jeans discovered dumped in a bag near her morgan hill home. but it was the defense team's turn today and attorney al lopez said dna protocol was not followed and the bag was contaminated. >> i think the defense did a good job in establishing that the protocols of the dna evidence collection were not followed and the prosecution will now have to shore that up through their own experts. >> reporter: defense attorneys also tore apart the district attorney's assertion that garcia-torres tried to kidnap three women separately in the parking lots of two safeway stores in morgan hill in 2009, three years before sierra lamar disappeared. not one of the three victims could pick out garcia-torres in a photo lineup. garcia-torres continued to look composed as he listened to attorneys talk about him and the evidence that may or may not lead to his conviction.
