Cincinnati Zoo: Parents Under Investigation After Gorilla Shooting

Breaking News

Cincinnati police are zeroing in on the parents of the 3-year-old boy who fell into Harambe the gorilla's enclosure ... a strong sign they could still be charged with a crime.

Cincy PD says they are reviewing "the actions of the parents/family that led up to the incident." Cops make it clear they're NOT focusing on the Cincinnati Zoo -- since that falls under the United States Department of Agriculture's jurisdiction.

Critics have called for the parents -- Michelle Gregg and Deonne Dickerson -- to face negligence charges ... blaming them for setting in motion the chain of events that led to Harambe's death.

Dickerson was not at the zoo when it all went down.
