Authorities are still searching for the mother of a newborn baby that was found next to an apartment complex dumpster in Riverside over the weekend.

A newborn dropped next to a dumpster outside a Riverside apartment complex was in stable condition Tuesday, as authorities initiated a search for his mother, encouraging her or anyone who may know her to come forward.

Officers responded to an apartment complex in the 3800 block of Jackson Street, near Magnolia Avenue and north of the 91 Freeway, after multiple callers reported a baby crying next to a dumpster, said Officer Ryan Railsback with the Riverside Police Department.
