Jennifer Catcheway's parents join search for Christopher Guimond

Family members of Christopher Guimond continue to search for the missing 48-year-old Winnipeg man, and on Monday they were joined by the parents of another missing Manitoban, Jennifer Catcheway.

"It breaks my heart," Bernice Catcheway, who is Jennifer's mother and a cousin of Guimond, told CBC News.

"It really breaks my heart because I know what they're going through."

Guimond has been missing since April 7, when he was last seen getting off a southbound transit bus on Pembina Highway and Plaza Drive that night.

His relatives and friends have been searching for him around Winnipeg. On Monday, they scoured the bush under the south Perimeter bridge.

Bernice Catcheway and her husband, Wilfred Catcheway, say they know how important help can be in searching for a loved one who has gone missing.

"If you live by the riverbank or if you can make it to the riverbank, then we need the public to come out," she said.

"We need to find them. It's too long already."

Teen disappeared in 2008

Jennifer Catcheway disappeared in June 2008, as she was heading to Portage la Prairie, Man., for her 18th birthday party.

In September 2009, Manitoba RCMP said they were treating the teen's disappearance as a homicide investigation. However, no trace of her has ever been found.

Investigators said they believe Catcheway's body is somewhere between Grand Rapids, Man., and Portage la Prairie.

Her parents, who have been searching for her every year, say search efforts will continue this summer in Grand Rapids.

In the meantime, the couple is sharing their experience with Guimond's family.

"The pain is there of not knowing where he is, and guessing what happened and is he alive," said Wilfred Catcheway.

Guimond's mother, Dorothy Starr, said not knowing where to start searching for her son — the oldest of seven children — has been difficult for her.

At the same time, Starr said, "I'm glad to see the kids get together and try and find him, doing anything we can to find him."
