Advocates of Maryland's Safe Haven Law spoke out after police said a mother reported Tuesday that she threw her dead baby in a Bel Air Dumpster.

Police said the mother reported that she'd given birth and put the infant, who she claimed was stillborn, in a Dumpster on Todd Road near Fairwood Road.

Investigators said they found the baby's body wrapped in a plastic bag, and the mother is cooperating with the investigation.
