Matthew Ethington II, 26, and Maria Martin, 22, were found dead Sunday at a home in Livonia, Michigan. Police said both officers were on the force for fewer than five years, according to FOX 2 Detroit. 

Investigators say Martin was shot multiple times, and Ethington died from a single gunshot wound that appeared to be self-inflicted. It has not been determined exactly when the shooting happened.
