An empty storefront and “For Lease” sign is all that’s left of Schroeder Piano Company & Piano Rentals, Inc., at 5680 La Jolla Blvd. in Bird Rock. The merchant has vacated the premises following the recent filing of 14 criminal charges against owner Peter Schroeder, ranging from financial elder abuse to embezzlement and grand theft. Several former customers of the establishment have stepped forward during a months-long investigation to allege that they were swindled in their dealings with the Schroeders.
