				 Zoo surveillance 
				cameras showed P-22 prowling around the zoo the night of the 
				koala's violent death, zoo director John Lewis told a news 
				conference. 
				 
				"Unfortunately, these types of incidents happen when we have a 
				zoo in such close proximity to one of the largest urban parks in 
				the country," Deputy Los Angeles Mayor Barbara Romero said in a 
				statement. 
				 
				Zoo cameras did not capture P-22 in the act, but officials said 
				there is ample evidence to support their belief that the cougar 
				found his way into the marsupial enclosure before making off 
				with the koala, named Killarney. 
				 
				P-22 appears to have jumped an 8-foot (2.4-meter) wall 
				protecting the koalas before making off with Killarney, who 
				weighed at least 15 pounds (6.8 kg), Lewis said. Parts of her 
				mangled body were found a short distance away. Only a large 
				predator could manage that, he said. 
				 
				Killarney may have been especially vulnerable to attack because 
				she had a habit of spending time on the ground after dark while 
				most of the other koalas stayed in the trees. 
				 
				Zoo officials said they have temporarily moved the remaining 10 
				koalas indoors around the clock, with most of the other zoo 
				animals moving inside every night. 
				 
				P-22's name was given by biologists studying mountain lions in 
				Southern California. It combines the first letter of "puma" with 
				the number that indicates he was the 22nd large cat tagged for 
				the study. 
				 
				He lives in 4,000-acre (1,619-hectare) Griffith Park, which 
				includes both wild sections and the zoo, and had been on zoo 
				grounds before without "bothering any of the animals or being a 
				nuisance," Lewis said. 
				 
				Last year, P-22 touched off a media frenzy after he was 
				discovered hiding in the crawl space under a Los Angeles house. 
				He stole away undetected in the dead of night.
