On March 19, 2015, Gjok Deda, a hulking 50-year-old from the East Bronx, brutally pummeled to death his diminutive downstairs neighbor, 68-year-old Ronald Antonucci, in a fight over parking, police said. He was charged with manslaughter four days later.

Last week, like so many felony defendants in the Bronx who go on trial, he walked free.

Prosecutors alleged that Deda, a contractor, picked a fight with Antonucci after the older man backed his car near where Deda was walking with his two daughters on Stadium Avenue in the Country Club section.

A witness told authorities that during the spat, the 6-foot-3, 220-pound Deda socked 5-foot-8 Antonucci in the head, according to court papers.

After spending over two years at Rikers Island, where he was held without bail, Deda was finally tried this month in Bronx Supreme Court, and jurors on Wednesday acquitted him.

His lawyer, Dennis Ring, argued that surveillance video failed to capture the episode, that a key eyewitness was inconsistent, and that the alleged victim had heart problems.

“We don’t know what happened, and they failed to show what happened,” Ring said of Bronx prosecutors.
