The backstory:

FOX 2 confirmed with police that the three bodies were of the suspect's ex-girlfriend, her mother and her 9-year-old niece. Officials say the man allegedly shot the mother and ex-girlfriend then stabbed the 9-year-old to death. 

From there, he allegedly drove their bodies across town to the city's west side where they wer burned inside the car. 

The grim discovery was made on the city's west side at Milford and 30th streets at 5:50 a.m. when Detroit Fire responded to a car fire.

Once the fire was extinguished, firefighters found three bodies inside, burned beyond recognition.

Police then performed a search warrant at a home on the city’s east side which revealed a homicide scene. Inside the house was a 4-year-old boy who had been left alone there for an undisclosed amount of time. 

He is related to the murder victims.
