A 52-year-old Mountain View woman has been arrested for allegedly trying to burn down her parents' Los Altos home early Saturday morning.

Police said three people were inside the house, located just behind Mountain View High School on the 1700 block of Hawkins Drive, when the fire broke out at 2 a.m., but no one was injured. The fire was substantial enough that the house has become "uninhabitable," according to the county fire department.

Police say the suspect, Jann Gilkey, was stopped by Los Altos police as she drove from the scene of the fire with her car's headlights off. She was not arrested at that time because the officer was concerned with the fire. "His interest was if he had to do any evacuations," said Los Altos police agent Mark Laranjo.

She was later arrested at her house on the 2200 block of Latham Street. She is being charged with burglary, arson and attempted murder.

"We believe it [the motive] to be financial in nature," Laranjo said. He added that "I believe she was adopted."

Gilkey has been booked in county jail without bail.
