Authorities on Friday afternoon ended their search of a Northwest San Antonio greenbelt for evidence related to missing child Lina Khil, according to a police statement. “After two days of following up on a potential lead received, SAPD and our partners have exhausted all resources and have determined that the tip was not credible,” San Antonio Police Department Public Information Officer Ricardo Guzman said via email. SAPD and the FBI earlier this week began combing through the greenbelt not far wfrom the playground where Khil was last seen before disappearing two years ago.
