Kate Gosselin’s sextuplets were all smiles during a Halloween family photo, but missing from the group was her troubled son Collin. Over one year after he was admitted to a treatment facility, the 13-year-old is still away from his family.

“I had a trick-or-treating date with a couple of cute pink Dinosaurs and a few adorable Astronauts,” Gosselin, 42, captioned the photo of Alexis, Leah, Hannah, Aaden, and Joel. “Happy Halloween!”

Noticeably missing from the family photo is Collin. Fans were outraged that he wasn’t with his family on the holiday.

“Collin should be home. This is terrible,” one commenter wrote, as another fired, “No Collin? This is sad. It's like he's not even a part of your family anymore... What's it been like 3 years now he's been gone. Imagine how Collin feels.”

Gosselin revealed in August 2016 that she enrolled him in a program away from home because he has “special needs.”
