According to the government’s evidence, on Aug. 28, 2014, Gutierrez contacted an undercover officer with the FBI’s Child Exploitation Task Force, who had posted an ad on a social network site. Over the next few days, Gutierrez engaged in e-mail, phone, and text message conversations with the undercover officer, whom the defendant believed was the father of an under-aged girl. During this period of time, Gutierrez arranged with the undercover officer to meet for the purpose of engaging in sexual acts with the child.
