Police Believe Body of Child Found in Texas Motel Is 6-Year-Old Samuel Olson. His Father’s Girlfriend Now Faces Evidence Tampering Charge. Jerry Lambe Samuel Olson, Theresa Balboa Police in Houston believe that the body of a child discovered stuffed inside a tote bag in a Texas motel room is likely that of 6-year-old boy Samuel Olson, who was reported missing last week. The girlfriend of the boy’s father was arrested and charged with evidence tampering, Houston Police Assistant Chief Heather Morris said during a Wednesday press conference. According to Morris, 29-year-old Theresa Balboa filed the initial missing persons report for Olson on Thursday evening, but the story she told officers began to unravel as the investigation progressed. Balboa told officers that at approximately 7 a.m. on Thursday morning she saw the boy’s mother speaking to a police officer at the front of the residence. Balboa said the officer told her that she would “go to jail for kidnapping if she did not return Samuel to the mother.”
