| The Queen Anne-style home in San Francisco's exclusive 
				Pacific Heights area had burn marks on the front and garage 
				doors after someone used gasoline to light the fire on Monday 
				evening, police spokesman Albie Esparza said.
 “The homeowner smelled smoke and went to the front door and 
				noticed the front door mat was on fire. The homeowner quickly 
				doused the flames and contacted authorities,” Esparza said.
 
 The fire, which caused only slight damage, is under 
				investigation by the joint police-fire department arson task 
				force.
 
 “We're looking at a former patient of the doctor who lives at 
				the residence as a person of interest,” Esparza said. “There was 
				a previous interaction between the two just prior to the fire. 
				That information was provided to us by the homeowner. We're 
				aggressively pursuing those leads.”
 
 The patient's name was not released. No other details about the 
				issue between the patient and doctor were disclosed.
 
 The home is a popular stop for tourists and became the site of a 
				makeshift memorial after Williams committed suicide in August. 
				Hundreds of mourners gathered outside the house, leaving flowers 
				and cards.
 
 It was purchased in 1997 by Dr. Douglas K. Ousterhout, who told 
				NBC Bay Area last summer he was the perfect person to own a 
				house featured in a movie about a man who disguises himself as 
				an elderly female nanny. Ousterhout is a craniofacial surgeon 
				who performs procedures on transgender people.
 
 "I turn boys' faces into girls' faces," he told the local news 
				station in August. “It seemed only natural” to buy the house.
 
 As for the people who flock there, he said, "It’s not a 
				problem."
