Abbygail Dice would have celebrated her first birthday today.

Tonight, there will be a vigil to remember the St. Thomas infant who disappeared from her apartment in September of last year.

Organizer Vicki Wooley says people will gather at Hawk Cliff near Port Stanley tonight at six to mourn her loss and demand answers.

Police believe Abbygail's body may have been thrown off the cliff and into Lake Erie.

Her mother, 32-year old Sara Whittington, is charged with Causing an Indignity to a Human Body.
