Family members have confirmed the identity of a toddler whose dead body was found outside an Edmonton church.

Family members identified the boy as Anthony Joseph Raine to CTV Edmonton.

Homicide investigators were interviewing a man and woman "believed to be responsible" for the death of the toddler whose body was found outside a Edmonton church, police said Sunday.

A 26-year-old man and 25-year-old woman were arrested on Saturday evening, and police say they are not looking for any additional suspects.

"No charges have been officially laid at this time," police said Sunday in a release.

Investigators have said they believe the boy was left near the Good Shepherd Anglican Church on Tuesday morning, three days before his body was found on Friday by a passerby.

No information has been released about the relationship between the two people in custody and the little boy, who police have not identified but have estimated was about 20 months old.

Police said they expected to release more information after charges have been laid and an autopsy scheduled for Monday is completed.
