Nova Scotia Health Authority (NSHA) is requesting the public assistance’s in locating 27-year-old patient Marcel David Lawrence, who has gone missing from a Dartmouth hospital.

The NSHA describes Lawrence as an African-Canadian man with brown eyes and short, dark hair. He stands six feet tall and weighs 232 pounds and has several tattoos on his face and neck.

He was last seen wearing a grey hoodie over a red T-shirt, white pants and a pair of red and white sneakers.

Anyone with information is asked to contact their local law enforcement agency.
