A jury has convicted a D.C. police officer of two counts of first-degree murder in the deaths of his mistress and their baby daughter.
During the closing arguments, the state described Richmond Phillips as a liar, cheater and user of women. The prosecution claimed Phillips spun a web of lies so his wife wouldn't find out about his affair and the child he fathered with Wynetta Wright.
Authorities alleged that Phillips, 39, fatally shot Wright near Hillcrest Heights in May 2011.
Phillips and Wright were scheduled to appear in court for a child support hearing just before both Wright and their daughter went missing, police say. Wright's body was later found in Oxon Run Stream Valley Park, while Jaylin was found inside a car in the 2400 block of Southern Avenue.
With a personal hand gun, a state attorney said Phillips used his left hand to shoot and kill Wright. Evidence shows he then dragged her body to a nearby wooded area, they explained.
Phillips then drove Wright's car with their daughter inside and allegedly parked the car, leaving his daughter to "bake and cook until she was dead," prosecutors said.
Defense attorneys questioned 37 seconds in the timeline of the crime. They argued Phillips could not have had time to move Wright's body.
They also pointed to video from nearby cameras that didn't catch the murder and reminded the jury no gun was ever found. Witnesses also never came forward.
Phillips was also convicted on handgun and child abuse charges among other charges.
Prosecutors say Phillips faces life without the possibility of parole plus 20 years at sentencing March 22.
