A Massachusetts man facing charges in connection with the discovery of human body parts in a duffel bag in Cambridge has been ordered held on $1 million bail.

Carlos Colina pleaded not guilty Monday 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 first were found in a discarded duffel bag outside a Biogen Inc. building Saturday. More parts were found in a Colina's apartment building across the street.

According to the police report, a saw, rope and cleaning supplies were found in Colina's apartment. His attorney could not immediately be determined.

The victim was identified as Jonathan Camilien.

Middlesex District Attorney Marian Ryan says the death is considered a homicide.
