San Francisco Police Arrest 25-Year-Old Woman in “Mrs. Doubtfire” Home Fires

San Francisco police have arrested 25-year-old Tyqwon Eugenen Welch of Los Angeles on suspicion of setting fire to the famous "Mrs. Doubtfire" house, police said.

Arson investigators took Welch into custody Wednesday in San Jose around 10 a.m. after getting information on her whereabouts, Officer Albie Esparza told NBC Bay Area.

Welch was booked into San Francisco County Jail on suspicion of attempted murder, criminal threats, trespassing, arson and possession of an incendiary device.

Police have not yet released a booking photo of Welch as the investigation is ongoing, Esparza said.

The arrest follows two small fires at the "Mrs. Doubtfire" home on Steiner Street, made famous by the 1993 film starring the late Robin Williams, which were set Monday about 8 p.m. The fires scorched the side of the garage and a doormat on the front porch.

Police were investigating whether the home was targeted because of what current owner Dr. Douglas K. Ousterhout, a plastic surgeon who works on transgender patients, does for a living.

Ousterhout told police investigators that a former patient of his could be behind the fires, making that person a likely suspect. Esparza said police is not discussing the relationship between the suspect and the victim at this time.

Ousterhout is considered among the nation's top craniofacial surgeons, and in a past interview with NBC Bay Area said he turns "boys' faces into girls' faces."

When Williams committed suicide in August, the Pacific Heights Victorian took on new meaning as mourners came to say good-bye to him with flowers, candles and loving messages.
