Police released a sketch of the suspect, but did not say whether that sketch led them to the person being questioned.

The death was ruled a homicide.

Streamwood police and paramedics responded to a call from the Salvation Army store in the 1000 block of South Barrington Road.

The body of the infant, which appeared to be full-term newborn, was found in the trash receptacle of a public washroom.

Police believe the mother gave birth between 10:15 a.m. and 11:15 a.m. Friday in the washroom.
