Family members of 17-year-old William Rosa, who's been missing since April 2, are pleading for the public's help.
"All we can do is just share get his face out there, have people recognize it, and ultimately just have people care," explained Jacquelyn Adams, Rosa's aunt.
Family members said Rosa left in the early hours last Tuesday morning. Adams said surveillance video from neighbors showed Rosa getting into a silver SUV which was last seen on Halls Mill Road near the I-65 overpass. They believe he met the person driving, online.
"I wouldn't expect William to reach out to strangers for help. I wouldn't expect William., this is the kid that just 2 weeks ago wouldn't necessarily go into the gas station to get a soda for himself because of his social anxiety around strangers," Adams said.
Adams said Rosa is not your typical teen. They believe Rosa may have a form of autism. She explained he's home schooled and doesn't interact well with strangers, so this is a shock for them.
"William is neurologically atypical. Very very high intellect, very high IQ super smart special kid but William is very much socially unaware, I might say socially awkward," she explained.
Thanks to help from ABC Signs and LAMAR advertising, they've painted the town with Rosa's face on billboards, banners, and signs throughout the area in hopes that someone has seen him.
"Wherever he is or whatever he's going through at some point he's likely going to surface in public and our only hope is that somebody will recognize him and say 'hey that's William Rosa," she said.
If you have seen Rosa or know anything about his whereabouts, call Mobile Police.
