Police initially responded to the home of Ashley Joy Davis, in the 1600 block of Langford Road, about 5:44 a.m. for a report of a suicidal person, but upon an initial investigation determined a simple assault had occurred at the residence, said Cpl. John Wachter, a police spokesman.
Unless police witness a simple assault, the victim must take his or her own initiative to file charges, Wachter said, so police left. He could not confirm whether Davis was involved in the assault, or how many people were in the home at the time.
Soon after, officers were called back to the home, where a fire had started in a second floor room, Wachter said. Firefighters responded and extinguished the blaze, and no one was injured. Arson detectives also responded to the home to investigate.
During the fire, Davis had been placed in a police vehicle "for safety because of the fire," Wachter said. It was not immediately clear whether she was placed in the vehicle against her will.
However, while in the patrol car, Davis kicked out one of the car's windows, Wachter said. She was then placed under arrest.
While she was being processed, Davis allegedly assaulted an officer, Wachter said.
She also "admitted that she set the fire because of an ongoing dispute," Wachter said.
Davis is charged with first-degree arson, second-degree assault, reckless endangerment and two counts of malicious destruction of property valued at more than $500.
She was being held Sunday afternoon at the Baltimore County Detention Center on $250,000 bail.
