The Dedham Police Department hung up some memorial bunting around the building to honor Officer Michael J. McMillan.
On Aug. 10, Officer McMillan died unexpectedly. He was a Dedham resident and a police officer for over nine years.
Chief Michael D'Entremont says that he was a highly valued member of the force because he was considered "the go-to-guy."
"It's a very big loss for the department," Officer D'Entremont said. "He was a highly respected member of the department so it's really a tragic loss for us. We'll miss everything about him."
Officer McMillan leaves behind his wife and five children. He was 48-years-old.
