ream for the kids,  Sierra said. He said he became jealous when Machado received a phone call.  You got into an argument with her because she received a phone call from another man?  Chaidez asked.  Yeah,  Sierra said. Prosecutors said Sierra kidnapped them at knifepoint and took them to the home where, days later, a neighbor who noticed the smell of decomposition found the three bodies in a master bedroom closet.  You exit the home through what door?  Chaidez asked.  The front door,  Sierra said. On cross-examination, defense attorney Joyce Brenner questioned Chaidez about his calm approach during the interview.  You kept this whole thing as calm as you possibly could so you could build a rapport with Mr. Sierra so you could get at the truth, right?  Brenner asked.  I already had a rapport with Mr. Sierra from our first interaction and our second interaction,  Chaidez said.  His behavior when it came to his wife's infidelity and affairs, I thought he was a bit too calm and relaxed for his responses. I am not saying someone wouldn't have a problem with their wife having an affair, but the way he was reacting to those questions didn't sit right with me.  On redirect, lead prosecutor Abbe Rifkin asked what prompted Sierra to stop providing the same false information.  When he was confronted about the DNA evidence found on the victims,  Chaidez said. Chaidez also described Sierra's demeanor when he was confronted with that evidence.  When he was confronted with that information, he clasped his hands, he stared down at the table for several seconds, he began to shake or quiver, and that is when he said something to the effect of,  I am going to tell you what happened,' and all that,  Chaidez said.
