Video: Trial Begins for Steven Schwally in Deadly Long Island Nail Salon Crash

Video shows coverage as the trial begins for Steven Schwally, the driver accused in the deadly crash into the Hawaii Nail and Spa in Deer Park, New York.

Prosecutors allege Schwally drove into the salon while heavily intoxicated, with authorities saying his blood alcohol level measured .17, more than twice the legal limit.

The crash killed four people, including off-duty NYPD officer Emilia Rennhack, salon owner Jiancai Chen, and workers Meizi Zhang and Yan Xu.

Schwally and his attorney do not deny he caused the collision but argue a medical issue involving his leg prevented him from taking his foot off the gas pedal.

Authorities say Schwally rejected a plea deal and could face decades in prison if convicted.
