(CBS) ZION, Ill. - Police were searching a landfill Friday in the search for Joshua Summeries, a 5-month-old Illinois boy who authorities say disappeared from his Zion home Wednesday morning, CBS Chicago reports.
Authorities have been questioning the mother's boyfriend as a person of interest in the case, according to the station.
Police say they have gathered good leads in the case, but still haven't found the missing baby.
"My hope is the baby's alive. My fear is now, that we're now in the point of looking at the worst," Zion Police Chief Wayne Brooks said Thursday, the station reports.
Joshua's mother originally told the police her son had been kidnapped by a man who grabbed the baby through a window. However, she later changed her story, claiming her boyfriend went to quiet Joshua early Wednesday morning and she hasn't seen her son since.
On Friday, police were sifting through trash at a Zion landfill in search for the boy.
Crews were reportedly using a backhoe to dig through a section of the landfill, as dozens of officers and others stood by in hardhats and orange vests. A cadaver dog was also at the landfill to assist in the search.
Zion officials delayed the normal Thursday garbage pickup, pushing it back one day, and asked residents to help search their trash for possible clues.
Police have reportedly searched several garbage cans in the neighborhood of Joshua's home. Authorities have labeled the garbage cans with red or green marks as they check them for evidence, the station reports.
"We are looking at garbage cans. We're looking in any place. We're looking for Joshua ... where ever a 5-month-old infant can be found," Brooks said. "Our hearts go out to that family, but any of us that are parents certainly would feel the same."
CBS Chicago reports a baby bottle was found Thursday night on the side of the road, just a few blocks from where Joshua was last seen.
