CHICAGO (AP) — A 39-year-old convicted felon appeared to be “hunting” for somebody to shoot shortly before he opened fire and killed a 9-year-old boy as he played in front of his Chicago home, a prosecutor said Tuesday.

Darrell Johnson has been charged with first-degree murder in the fatal shooting of Janari Ricks on Friday evening in the Cabrini-Green neighborhood. Johnson was ordered held without bond at a court hearing Tuesday.

Cook County Assistant State’s Attorney James Murphy told the judge that security video footage shows a man wearing a mask who they believe was Johnson looking through fences and into courtyards, apparently searching for his intended target.

Authorities have said Janari was not the gunman’s intended target.
