Markham parents charged in death of infant son

The parents of a one-month-old boy have been charged with second-degree murder in their child's death.

York Regional Police said Wednesday the boy's father Kien Phat Tran, 21, and mother Thi My Phuong Bui, 22, both of Markham, Ont., are in police custody and will appear in court today on second-degree murder charges.

Police say the investigation began last Thursday when the boy's parents brought the child to a local hospital without vital signs.

Police would like to hear from anyone who knows the family or has information about this case.
