evidence: MILWAUKEE, Wis. (WBAY) - Wisconsin launches a new missing-child alert system on Thursday. [...] Gov. Tony Evers signed the Prince Act in April to address gaps in Wisconsin’s Amber Alert System. The legislation revised and expanded the definition of a "person at risk" to include children. [...] "It’s my privilege to be able to tell you today the first missing child alert was issued earlier this week. It was based on a missing child here in Milwaukee and that child was recovered safely, so the alert is already having an impact," said Kaul.
