St. Paul teenager Alexandra Rodriguez has now been missing for 13 days, and her family says there's still no indication where she might have gone.

But their search for answers received a big helping hand from a national media figure on Thursday, bringing Alex's story to legions of social media users.

Over 27,000 people so far have shared HLN host Nancy Grace's Facebook post about Rodriquez, prompting a message of thanks "to everyone for helping us" from the Help Find Alex page.

While the circumstances of her disappearance on May 30 – when she was last seen walking her dog, a schnauzer named Pepper (who is also missing) – remain a mystery, her activities at school the day before her she vanished are being scrutinized.

The Pioneer Press reports the 16-year-old turned in her school-issued iPad a week earlier than required, something her aunt says is strange given Rodriguez's reliance on the electronic device.

According to the paper, police don't regard the disappearance as "suspicious."

Sgt. Paul Paulos told BringMeTheNews they don't believe she's a danger to herself or others, saying she's left home before but later returned.

It is an active investigation, Paulos said, but there are no police search parties planned at this time

The operator of the Help Find Alex Facebook page however replied to a comment saying they've been "discussing maps, flyers and potential searches and will post on this page when we have a plan," noting at this point they've gone door-to-door and posted flyers.
