Several cars were buried in debris after a garage wall collapsed in Brooklyn Friday morning, authorities say.
No one was injured when the 20 foot-by-20 foot wall fell in Crown Heights around 7 a.m. Four cars were flattened underneath collapse.
NYPD deployed K9 units to scour the rubble on Crown Street to make sure no one was trapped underneath, and checked neighbors' security camera footage as well.
The collapse was likely caused by this week's heavy downpours, which possibly made the supported retaining wall even weaker, according to fire officials.
Forensic engineers are trying to determine the integrity of the structure. It's not clear what caused the wall to fall.
