The Winnipeg Police Service is launching a new campaign to help solve dozens of missing or murdered persons’ cases.

And this campaign will be in every drivers face.

Starting November 30, you'll start seeing posters with pictures of 28 missing or murdered people on the sides of buses around the city.

One asks "help find my killer."

Another says "do you know who killed me?"

And the last simply says "help bring me home."

Police hope they will jog someone's memory.

"We owe them and their families these answers," said Const. Jason Michalyshen. "And this is a plea once again, that we need the public's assistance."

So far, Project Devote has solved only one case.

Traigo Andretti was convicted and later sentenced to life in prison for the murder of Myrna Letandre.

Anyone with information can call the Project Devote tip line at 1-888-673-3316, or Manitoba Crime Stoppers at 1-800-222-TIPS (8477).
