“Baby Doe” was found Saturday around 9 p.m. at RTA’s stop at Superior and E. 105th St.
The baby was with a man who could not verify his relationship with the child, a Cuyahoga County spokeswoman said.
RTA is also asking for help to identify a woman at the scene.
RTA says she’s a person of interest who was on the scene but was not providing verifiable identification.
The baby girl, between 3-6 months old, is “doing well” in foster care.
Anyone who can identify the child should call 696-KIDS, 911 or local law enforcement.
