The McCann family is being joined by a number of volunteers who are giving their time to help circulate posters and flyers about the disappearance of Lyle and Marie McCann. The couple has now been missing for a month.

Volunteers gathered with family members in west Edmonton near 169th Street and 118th Avenue on Sunday afternoon to collect posters and tape. The group will distribute the posters at businesses and other public places off the Yellowhead Highway.

The family is hoping to circulate posters and flyers with information about the McCann's disappearance between west Edmonton, Spruce Grove, and Edson.

"The main accomplishment is finding our aunt and uncle, bottom line, finding them safe and bringing them home," said family member Stephen Carrol.

About two dozen volunteers joined the family in their efforts.

"If something like this happened to our parents, you would want people to step up and help you," said volunteer Katharyn Webb.

Lyle and Marie McCann have not been seen or heard from for a month. The McCanns left for Chilliwack, B.C. on July 3 towing their green Hyundai SUV behind their motorhome.

The McCann's burned-out motor home was found on July 5th near the Minnow Lake campground approximately 35 kilometres southeast of Edson. On July 16th, their green Hyundai SUV was located deep in the bush about 30 kilometres east of Edson near Carrot Creek.

Police still would like to hear from anyone who may have seen the McCann's 2006 Hyundai Tucson, licence plate ZPK 289, during the period of July 5th to the 16th.

Police have named Travis Vader a person of interest in the investigation, but no charges have been laid against him. He is currently being held in custody at the Edmonton Remand Centre.
