A man facing charges in connection with the discovery of human body parts inside a discarded duffel bag was ordered held on $1 million at his arraignment Monday.

Carlos Colina, 32, pleaded not guilty in Cambridge District Court to charges of being an accessory after the fact to assault and battery causing serious bodily injury and improper disposal of a body.

Remains, including a torso and limbs, first were found in a discarded duffel bag outside a Biogen building Saturday morning, according to the police report.

A head was found in a recycling bin in Colina's apartment building across the street, according to the police report.

Middlesex District Attorney Marian Ryan identified the victim as Jonathan Camilien, 26, of Somerville. She said the two men knew each other but did not give any details. Ryan said Colina has an earlier, pending assault and battery case in Middlesex County, but Camilien was not the alleged victim in that case.

She has said his death is considered a homicide, and that investigators are not seeking anyone else. She said analysis of evidence and more information from the medical examiner are needed to determine if additional charges are warranted.

A saw, rope and cleaning supplies were found in Colina's apartment, according to authorities.

According to the investigation, a neighbor reported hearing an argument coming from Colina's apartment Friday night, while Colina and Camilien were last seen returning to the building just after 11 p.m. Friday.

A man now identified as Colina was seen in surveillance video from nearby Biogen offices exiting the apartment building at about 4:15 a.m. Saturday carrying a duffel bag, authorities said. He returned to the apartment building empty handed.

Defense attorney John Cunha Jr. called it a sensational case.

"Obviously the circumstances of the case are sensational enough," he said. "I'm not going to exacerbate it."

He later called it "a sad situation."
