No arrests have been made in connection with a June incident in which 187 baby barn swallows were killed at Lake Hefner, but officials said the investigation continues.
A special agent from the Edmond office of the U.S. Fish and Wildlife Department investigated the incident. His findings were turned over to the U.S. Attorney's office, but no charges have been filed.
On June 8, a man who had rented a boat slip for his sailboat at the Gate 4 docks allegedly knocked down several dozen nests, killing the barn swallows, police said. The man said he was tired of the mess the birds were making at the dock.
The dock is owned and run by Oklahoma City. The man's privileges to the boat dock were revoked after the incident, a city spokeswoman said.
