A media campaign was launched Tuesday in an effort to bring in tips in 17 unsolved murders that occurred in Seattle since January 2010.

Some of the victims' families attended the unveiling.
"I think it could work, but it's also really hard as a family to see your child's picture up." said Monica Wood, mother of murder victim Franklin Wood.
Billboards and bus ads picture murder victim's faces and ask "Who Killed Me?"
"They know who they are and they need to come forward cause we are in pain," said Anne Williams, the great aunt of victim Desmond Jackson.
The campaign aims to break the no snitching culture that has impeded some murder investigations. "Don't Stay Silent," the billboards say.
"People have a moral obligation to come forward," Deputy Chief Nick Metz told those gathered at the campaing launch.
The billboards feature the images of victims Danny Vega, Nicole Westbrook, and Desmond Jackson.
Desmond's mother, Marlo Williams, tearfully begged the public, "If there's anybody with information that can help solve Desmond's case, please, please come forward."
