The “Booth & Tucker” sign that hung on the wall behind the receptionist’s desk was taken down Monday afternoon, signifying the end of what was arguably one of Pennsylvania’s most well-known and successful minority-owned law firms.

Founding partner Christopher R. Booth Jr. left Philadelphia-based litigation boutique Booth & Tucker April 27, and the firm officially became the Tucker Law Group that same day.The reason for Booth’s departure, as well as what might be next for him, appeared to be a mystery on Monday.
