A Wilton man accused of killing his neighbor in what police said was an unprovoked attack on his neighbor intends to go with an insanity defense, according to his attorney.
Sebastian Andrews, 31, appeared in Stamford Superior Court Wednesday where head public defender Jared Milbrandt said his client plans to plead not guilty by reason of insanity in the death of Arinze Ukachukwu, 39.
Ukachukwu’s family made the trip from Brooklyn to be at the court hearing. Several of them shook their heads in dismay as Andrews was led in. They appeared visibly upset upon hearing Milbrandt’s expected defense.
“My brother was an inspirational guy,” said Princess Ukachukwu, getting emotional. “He was a good kid. He didn't deserve to die.”
Ukachukwu was killed at his home on Partrick Lane on March 21. He, his wife, and their young son had only recently moved to the neighborhood. They’d been seeking a quieter life in the suburbs after living in Brooklyn, according to his sister.
Ukachukwu’s homicide was the first in Wilton since 2012.
Police said they responded to his home after a 911 call from Andrews' dad, who said he’d looked out his window and seen his son stab Ukachukwu in Ukachukwu's driveway, then drag his body into the garage.
In an interview with police, Andrews said he’d gone over to his neighbor’s house to get a tool and because he’d found his neighbor “trespassing on his property several times, specifically in his attic,” according to Andrews’ arrest warrant. He stated that Ukachukwu looked at him “with eyes that looked insane” and took him to the garage, the warrant said. Andrews also claimed Ukachukwu “was about to hit him with something” so Andrews attacked him with a knife, according to the warrant.
Deputy Chief Robert Cipolla previously told News 12 there was no evidence so far that substantiated Andrews’ story.
“I came here today, taking time off from work, to stand for him. And I'm going to make sure I seek justice for my brother. All who were involved will be revealed. Every factor must be revealed, and I’m going to make certain of this as the oldest sister,” Princess Ukachukwu said after the hearing.
Andrews is due back in court Aug. 1. He remains in custody on $2 million bond.
