This week saw a missing girl safely returned to her family after nine months—but her disappearance in Conway, New Hampshire remains mysterious. Authorities are looking into the "facts and circumstances" that led to Abigail Hernandez going missing, Reuters reports. Police have released a sketch of the man said to have picked up the 15-year-old in his truck when she disappeared, but it's not certain whether he took her "against her will, enticed her away, detained her, or concealed her whereabouts for the last nine months," officials say.
"We continue to say we have a number of questions we don't have answers to," an assistant attorney general says, per the AP. Investigators lacked evidence of foul play, she adds. But "a child cannot do this on their own with this level of sophistication to stay off the grid. Especially a child of this age—they live through phones and social media." A criminal law expert points to the strangeness of the story. "You never get cases like this where you're at the end game of the case, and it's completely unclear what happened," he says.
