Their bodies were found in an apartment complex in the area of Six Mile and Farmington roads in Livonia, police say.

Livonia police officers were on patrol when they were flagged down by a family member for a well-being check, Livonia Capt. Gregory Yon told FOX 2. Officers made entry and found two people dead.

Detroit Police Chief James White says the incident appears to be domestic in nature, an apparent murder-suicide. The 26-year-old male officer and 22-year-old female officer were in a relationship.

"It’s a sad day for our department," White said. He would not release the officer's names on the scene. 

An infant was found unharmed inside the residence and was turned over to a family member, police said.
