California wildlife experts and cops say someone has been shooting sea lions whose corpses are washing up along the Malibu coast.

"I have no idea why people would shoot a sea lion," Jonsie Ross of the California Wildlife Center told ABC News.

Since August, four sea lions have washed up along the Malibu coast. The most recent were on Oct. 10 and 11.

Mike Remski, marine mammal rehabilitation manager at the California Wildlife Center acknowledges the higher number of incidences in recent weeks.

"The past couple of weeks, there have been more than usual animals stranding on the beaches. We are getting a greater number with bullet holes in them," Remski said. "For the ones that wash-up dead, necropsies are done and we try to retrieve the bullets to find a cause of death. If they're alive, they're sent immediately to the rehabilitation center [Marine Mammal Care Center (MMCC)] in San Pedro."

Not only is shooting these animals inhumane, it's also illegal.
