From the outside, the home of suspected serial killer Lonnie Franklin Jr. looked like something out of a fairytale; the place where the elf or the leprechaun lives. Mint-green with a pointy rooftop and surrounded by a wrought-iron fence, the low-slung house stood out among the neighborhood's crème-colored bungalows.

Franklin, who police believe killed at least 10 women and maybe many more, shared this house with his wife of 32 years. Inside, framed family photos covered living room tables and bookshelves. Nearby, in the cluttered office, stood a cot where Franklin's mother-in-law sometimes slept. His grandchildren, who often came by, had their own room, filled with plush toys.

But this respectable-looking home in south Los Angeles, detectives say, was really a house of horrors—the place where the so-called Grim Sleeper kept all his morbid trophies.
