This sign over the freeway

I have been driving by these signs for the last couple of days but I don't think these signs are working because they still haven't caught the couple. https://www.usatoday.com/story/news/nation/2019/08/29/arizona-couple-accused-murder-escape-prison-guards-manhunt-begins/2150987001/
Note: I've been wanting to take my own photo of this sign, but have been unable to since I'm always driving. This photo is from the article.
