Montreal police are investigating if an object found in a public park Sunday evening is a body part.

The suspicious object was found by the police’s major crime unit in Angrignon Park in the city’s south end.

The park is closed to the public and police say the object has been sent to a lab.

Police spokesperson Anie Lemieux said the object would be analyzed by police to determine whether or not it is in fact a human head, and if so, if it is linked to the murder of Concordia University student Jun Lin.

Lin, a 33-year-old computer engineering student and Chinese national, was gruesomely murdered and dismembered in late May. His hands and feet were mailed to offices of the federal Conservative and Liberal parties and to Vancouver schools. His torso was found in a suitcase outside a Montreal apartment and some body parts, including his head, are still missing.

Charged with Lin’s murder is Luka Rocco Magnotta, a 29-year-old porn actor and model. Magnotta appeared in Montreal court late last month where he pleaded not guilty to the multiple charges against him.
