The Oakland County Prosecutor's Office is reviewing a report on the arson early Oct. 25 that burned through the singer's unoccupied, 10,000-square-foot home in this Detroit suburb.
``No one's in custody, but we believe we know who set it,'' Bloomfield Township Police Chief Jeffrey Werner told The Detroit News for a Tuesday story.
Prosecutor David Gorcyca told The Oakland Press of Pontiac that charges could be issued as early as Tuesday.
``There are three separate points of origin in one room in the house,'' Gorcyca said. ``The chemicals are similar to, and may be, lighter fluid. A known accelerant was used.''
Franklin, 60, primarily uses the house for storage and lives in another in the township. She was on tour at the time of the blaze.
