A suburban couple, whose dismembered bodies were pulled from the Detroit River last week, lived with a man arrested in connection with their homicide.

On Thursday, police arrested a man they say is connected to the murders of 42-year-old Chris Hall and 32-year-old Danielle Greenway of Allen Park, a community of 27,000 people just outside Detroit.

The suspect’s identity is being withheld, but police confirmed Monday he had recently moved in with the deceased. He is facing several unspecified charges and is expected to appear in court Monday afternoon.

Police launched their investigation into the deaths of the Allen Park couple last Tuesday, when a fisherman spotted their torsos — which were missing their heads, arms and legs — floating in the river near Detroit’s east end.

At the time, Detroit Police Eastern District commander Steven Dolunt said the gruesome nature of the crime suggested it was meant to send a message. However, he could not say who sent the threat or who it was meant for.

A medical examiner’s report reveals Hall died of multiple gunshot wounds, while Greenway died of a gunshot wound to the head.
