Albany, N.Y. (WNYT) – It was on May 29, 2024, when the lives of Shogun co-owner Su Wen Zheng and his family were changed forever.

43-year-old Lucas Healey was drinking and eating at Shogun on Madison Avenue when he walked out of the restaurant after paying only $50 of a $425 tab.

Surveillance video from a nearby business shows him carrying takeout bags, and the restaurant employees confront him. He starts throwing punches.

He hit the owner, knocking him unconscious. Su Wen’s head smashed into the concrete sidewalk and he suffered a traumatic brain injury.

He had to have emergency surgery, and he was in a coma for a time.

“It’s really just disturbing that one human being would do that to another and take joy, because that’s one of the things in the video that shocked me, just as a human being, seeing the defendant- now convicted- jumping around and acting like they were in a play boxing match, when there was a man pretty seriously injured on the ground,” said Albany County District Attorney Lee Kindlon.

Healey did not testify in his trial.

Prosecutors were asked what they thought made a difference for the jury.

“The testimony of all of the witnesses that we had,” said Assistant District Attorney Taylor Cupp. “Seeing video is one thing, but then hearing the testimony from all the witnesses who were there that day that observed it, they testified to what they saw, what they heard, and that– I think that was really emotional, as well.”

Healey had previously rejected a plea deal that would have gotten him 20 years in prison.

Now he’s facing up to 25 years, or maybe even more. If a judge finds persistent felon status, he could face life.

The victim was not well enough to testify in the trial.

“I can tell you that he is doing better than when this incident happened and the hope is that he is continuing to make strides to recover, but his life has been altered irrevocably,” said Assistant District Attorney Ryan Carty.

Healey is scheduled to be sentenced on March 28.
