Two sources close to the family of missing Aurora girl Aarone Thompson are confirming the death of Shely Lowe, the live-in girlfriend of Aarone's father.
Family spokesman Sam Riddle tells Denver-area broadcast outlets that Lowe died this morning of an apparent heart attack.
Lowe's attorney, Walter Gerash also confirmed her death.
Aurora police have been calling Lowe and the girl's father, Aaron Thompson, "persons of interest" in the child's disappearance and authorities announced last week a grand jury would be convened.
Both Riddle and Gerash blamed Lowe's death on stress from the ongoing investigation, and a jury's recent decision that the family's other children should NOT be returned to the couple.
