The affidavit stated that two dogs trained to detect the odor of decaying human tissue alerted on Sifuentes' Lincoln Navigator while it was parked at the Carrollton police station.
John Glenn student
Lisa McLaughlin, assistant superintendent for Western Heights Public Schools, said Gonzalez attended John Glenn Elementary school in Oklahoma City. McLaughlin said counselors were at the school Monday to help students in mourning.
School staff members are collecting funds for the fourth-grader and her family. Gonzalez's older brother is also a student in the district, McLaughlin said.
“We were just devastated to hear about her death,” McLaughlin said. “Certainly our thoughts and prayers are with her family.”
Carl Rusnok, spokesman for the U.S. Immigration and Customs Enforcement, said the agency placed a detainer with the Carrollton Police Department because they think Sifuentes is deportable.
“By issuing a detainer, ICE requests that a law enforcement agency notify ICE before releasing an alien and maintain custody of the subject for a period not to exceed 48 hours, excluding Saturdays, Sundays, and holidays, to allow ICE to assume custody,” Rusnok said. “If he's released from local custody for any reason, he'll be turned over to ICE.”
Mitchell said Sifuentes, who lives less than a mile from the apartment complex, had attended the gathering of friends and family at the apartment complex. He said relatives of Gonzalez's family were visiting from Mexico.
Carrollton police began searching Sunday night with helicopters and search dogs, said Jon Stovall, a police department spokesman.
Police also searched a red Chevy van owned by Jasmen's parents. Inside, officers found red fibers consistent with a red blanket. Relatives had told police that Jasmen had gone to sleep that night with a red blanket. The blanket is among items that police are searching for, according to the affidavits.
“Investigators observed that there were numerous discrepancies between the time lines and events of the evening as described by the occupants of the apartment,” one affidavit stated.
Mitchell said police also searched Sifuentes' Carrollton apartment and the apartment Jasmen's family was visiting.
“We recovered a lot of stuff, and they're still going through that,” Mitchell said. “We're still early on in this investigation.”
