A candlelight vigil and ecumenical prayer service to be held Monday night will mark the 23rd anniversary of Ilene's disappearance.
On the day she disappeared, Ilene had left school early after being excused from a physical education class, according to her family.
She walked home alone, and was last seen at the intersection of San Ramon Road and Amador Valley Boulevard.
Monday's vigil will retrace her steps along that route, beginning at Wells Middle School at 6800 Penn Drive.
Mike and Maddi Misheloff, along with Ilene's twin brother, Brian, will lead the walk as they have done every year since Ilene went missing.
The vigil will begin at 7 p.m. and will conclude with a short prayer service at St. Raymond Catholic Church at 11555 Shannon Ave. in Dublin.
The Misheloffs say they are hoping someone has information and will come forward.
A picture of what Ilene would look like today can be found on the website www.find-ilene.orgalong with information about rewards and tips for preventing child abductions.
