A D.C. police officer is scheduled to go to trial this week for the murder of his girlfriend and their 1-year-old daughter.

Richmond Phillips has been charged with first- and second-degree murder in the death of Wynetta Wright, 20, and manslaughter in the death of Wright's daughter, Jaylin.

Phillips, a vice detective, was arrested in June 2011 shortly after Wright's body was found in the Oxon Run Stream Valley Park in Prince George's County with what police say was obvious trauma on her body. Her daughter was later found dead in a car seat in Wright's nearby car.

Wright and her daughter were last seen the night before she was scheduled to go to court for a paternity case against Phillips, who was married.

DNA tests later confirmed that Phillips was the father.

Jury selection is scheduled to begin on Tuesday in Upper Marlboro.
