Authorities say a Prince George's County police officer has been arrested and charged with murder in connection to a double shooting at a McDonald's restaurant parking lot in Waldorf.
Officer Richard Conway faces several charges, including first-degree murder, after a May 20th shooting left a man dead and his ex-wife hospitalized.
Conway's mother, Caroline, was arrested last week and also charged with first-degree murder in this case.
Police say the Conways conspired to kill Richard's ex-wife and mother of his children, Krystal, along with Krystal's current husband, 25-year-old Robert Mange.
Police say Caroline Conway was the shooter and the reason for it was a child custody dispute.
"We followed the investigative leads, we were able to quickly apprehend her, and when we had an opportunity to question her, she admitted to the shooting," said Charles County Sheriff Troy Berry.
Caroline confessed to police that she used her son's gun from his job at the Prince George's County Police Department. The murder weapon has not yet been found. Shell casings from the same ammunition used by Prince George's County police were found at the crime scene.
The murder happened at dinner time last Wednesday at a McDonald's restaurant where Krystal and Robert Mange were picking up her two kids from the Conways.
Caroline Conway got in the unlocked back door of the Mange's vehicle and was carrying her son's service weapon. Robert Mange tried to wrestle the gun away from her, but instead, she shot him several times in the torso.
Krystal went out the side door to try to run away, but Caroline followed her and shot her in the back.
According to prosecutors, text messages between the mother and son show that Richard Conway was part of the planning of the murder -- and the cover up afterwards.
"The evidence we believe shows he conspired with his mother ahead of time and assisted her in making the crime succeed," said Charles County State's Attorney Anthony Covington. "That's first-degree murder."
Conway worked for the Prince George's County Police Department for three years.
"I think any time a police officer, who has sworn to protect and serve, commits any crime, but especially murder, it does shock the conscience," said Covington.
Prince George's County police has suspended Conway without pay.
Both suspects are sitting behind bars without bond at the Charles County Detention Center.
"The charges this officer faces are deeply troubling to me, but his actions are his own and not a reflection of the over 1,700 men and women that serve our community day in and day out with professionalism and integrity," said Prince George's County Police Chief Mark Magaw.
Police say Krystal Mange is out of the hospital.
Her family has been taking care of the children, a 4-year-old boy and 2-year-old girl. Sadly, these children lost so much that day in a family fight over them.
