Silent Observer, in partnership with the family of Martin Martinez, has increased the reward to up to $10,000 for information leading to the arrest of those responsible for Martin’s tragic killing on January 27, 2024. This reward increase and an impactful billboard campaign, titled “You Know Who Killed Me,” are efforts to seek justice and bring closure to his family. The billboards, featuring Martin’s photo, will appear in the Wyoming and Grand Rapids area to remind the community that every tip matters.
