P-30 as an adult.
On September 9, biologists hiked into Topanga State Park to look for P-30 after his radio collar sent out a mortality signal. He was found dead with no obvious signs of injury or trauma. The cause of death for this otherwise healthy six-year-old male was anticoagulant rodenticide poisoning. He is one of the more notable mountain lions of the study because he was the first male lion kitten to have been marked at the den and then to have survived long enough in the Santa Monica's to reach adulthood and establish a home range.
