Spokane police are investigating the death of a baby boy and say his mother's boyfriend is the only suspect.

 The 1-year-old boy was not breathing when officers arrived at an East Everett Avenue home in Hillyard just before 5 p.m., according to a news release by Lt. Dave McGovern.

"Detectives are interviewing the family and are currently questioning a suspect, the boyfriend of the child’s mother," McGovern wrote at 8 p.m. "No arrests have been made as of yet. There are no other outstanding suspects. The investigation is ongoing and there is no further information at this time."
