GREENFIELD — The man accused of barricading himself in an Elm Street home on Friday morning, resulting in a six-hour standoff with police, pleaded not guilty to home invasion and assault charges in Greenfield District Court on Monday.

William Judd, 57, of Greenfield, is accused of breaking into 221 Elm St. resident Chester Bai’s home, armed with a gun, early Friday morning, where he allegedly remained for about six hours, until Franklin County Regional Special Response Team officers removed him from an attic crawl space. He has been charged with home invasion, assault with a firearm, drug larceny, larceny, and assault with a dangerous weapon.

Judd, represented by attorney John Godleski, appeared before Justice Janine Simonian Monday morning. Godleski agreed to Assistant District Attorney Ryan Scott’s request that Judd’s dangerousness hearing be set for Thursday.

Given the significant amount of body camera footage captured by Greenfield Police, Response Team and State Police law enforcement, Simonian denied Godleski’s request for a discovery meeting Wednesday, deciding it was “not feasible” for the commonwealth to produce the evidence in two days.

At approximately 5:45 a.m. Friday, resident Chester Bai, of 221 Elm St., said he woke up to find a man with a ski mask and a gun “Army crawling” on his bedroom floor. Bai said a fight ensued and he was able to leave the single-family home and call the police.

“I woke up and I saw this guy Army crawling on my floor,” Bai said outside the Elm Street home Friday morning. “He hit me, so I hopped up into my wheelchair and I hit him in the back of the neck.”

According to Greenfield Police Chief Todd Dodge, Sgt. Emily Rowell-Kanash was the first officer to arrive on Elm Street after Bai called police, and she confirmed she saw what she believed to be a white male wearing red gloves inside the home through a window.

Law enforcement vehicles lined Elm Street near the intersection with Albert Avenue, operating drones and, at various points, flying them through the home. Dodge said Judd did not come out of hiding after police filled the space with CS gas, one of the most commonly used tear gases.

Judd was taken into custody at approximately 11:30 a.m., after which point police officers began searching the home for a firearm. He was transported by ambulance to Baystate Franklin Medical Center for evaluation. Dodge said he was likely overheated, dehydrated and irritated from gas exposure.

“He was up in the attic when they deployed numerous rounds of CS gas to try to get him out. I don’t know how he made it through that, other than the fact that he must have somehow been filtering his breathing up there,” Dodge said on Friday. “They had to actually go up and remove him physically from the attic.”
