Sandra Kaye Patterson, who also used the last names Thompson and Elliot, disappeared from Colorado Springs in 2009. She was 46 at the time and is described as white, 5 feet 4 inches to 5 feet 5 inches tall, 130 to 140 pounds, with brown hair and brown eyes, pierced ears, a scar on her lower lip and a mole near her right eye.

Sandra had documented struggles with mental illness and addiction and had lived in Tennessee, Nevada, Indiana and Illinois before relocating to Colorado Springs. Her then-boyfriend told police she left voluntarily and intended to move back to Tennessee or Nevada. Family members say she sometimes went out of touch for weeks but that this prolonged absence was uncharacteristic and deeply worrying; they have suggested she could be living among the homeless population.

Her case is classified as an endangered missing person case and remains an active cold case with the Colorado Springs Police Department. Did anyone in Tennessee, Nevada, Indiana or Illinois ever see Sandra after 2009, or did anyone know where she might have gone?
