The weak and woozy California sea lion found on a San Francisco Bay-area beach in December with buckshot embedded in its skull has become an all-too-common sight for wildlife officials.
Wildlife officials have seen a slight rise in the shooting of ocean mammals in recent years, and investigators often struggle to find a culprit. There are few witnesses to such shootings, making it nearly impossible to bring a case.
"We always try to do an investigation, but unless there's an eyewitness to the shooting it's hard to make a case for our enforcement folks," said Joe Cordaro, a wildlife biologist with the National Oceanic and Atmospheric Administration who tracks reports of the shootings.
