A motorcycle club called Hooligan Riders Trademark is organizing the "Bring Ayla Home" event Saturday at Big Moose Harley-Davidson in Portland.

Ayla Reynolds went missing more than five years ago while staying with her father, Justin DiPietro, his girlfriend and his sister in a Waterville home. Reynolds was 20 months old when she disappeared.

No one has been charged in her disappearance. Police say they believe those who were with her on the night she went missing know more than what they've told investigators.
