MILWAUKEE (CBS 58) -- Police are investigating after they say a driver caused three crashes, blocks apart.

Video captured the chaotic scene near Humboldt and Center in Milwaukee's Riverwest neighborhood. Police say the driver ran after flipping their car on the front lawn of a home.

Beverly Williams said the car came to a stop in her son's front yard, right where her granddaughter's inflatable pool would have been.

"She was just about to put her pool out right here and she heard a big boom," Williams said. "I thank the lord she was not out." 

Witnesses say the dangerous chain of events started with an argument outside a bar. 

No one was hurt.
