Police have charged a 25-year-old woman and 27-year-old man in connection with the death of a 3-year-old.

The investigation started March 6 just before 7:30 p.m., when Six Nations police were called to an address on Six Nations of the Grand River territory. The call was about a medical complaint.

But when police arrived, a 3-year-old boy was unresponsive inside the house. He was taken to Brantford hospital and was pronounced dead. 

On Thursday, police investigators from Ontario Provincial Police and Six Nations police charged the two adults with manslaughter and a number of other firearm and drug offences. 

They're both expected to appear in Brantford court at a later date.  

According to an obituary for the boy, the two adults charged were his parents.

"This incident was very traumatic for everyone involved in this investigation," Six Nations Police Chief Glenn Lickers said in a news release.

"And it is my hope that we can heal and come closer together as community to help protect all of our children."
