HYANNIS (CBS) – Using the protection of an armored vehicle, a SWAT team peered into windows as police investigated an apparent homicide in Hyannis Wednesday. Search dogs were at the ready as police moved in, surrounding a commercial building.

Officers blocked off Yarmouth Road, which runs along the Barnstable Municipal Airport. Crime scene tape went up around JJ’s Auto Service and Towing and detectives went to work.

The district attorney’s office will only say they are investigating an apparent homicide.

“The whole road was closed and I walk in the building where I work and a couple minutes later the police officer took everybody out,” said Marcelo Sousa, who works across the street from the business and lives next door. “Kind of dangerous the kids here and everything.”

He says there have never been any problems in the area.

“I’ve never seen anything like that happen before,” Sousa said.

Officers were called to the building in the early afternoon and hours later they were still at work.

“There wasn’t a large police presence in the neighborhood, they were mostly around the building,” said neighbor Cheryl Freeman.

With no announcement of any arrests, neighbors are still anxious for answers.

“It can be a little nerve-wracking especially if you don’t know if someone is still out running around so that can be a little daunting,” Freeman said.

The district attorney has yet to release the victim’s name.
