A Burlington County couple has been arrested and charged for their roles in the murder of a teen earlier this month in a Willingboro shopping center parking lot, announced Burlington County Prosecutor Scott Coffina and Willingboro Township Police Department Acting Public Safety Director Captain Ian Bucs on Saturday.

Willingboro Police were first to the scene on February 11, around 7:30 pm, at the Kennedy Plaza in the 400 block of John F. Kennedy Way, and in the parking lot, they found 19-year old Adam Janson of Burlington City/Burlington Township just outside of a pizza shop.

Through their investigation, police learned that Janson got into a car with 21-year old Knowah Crowderparham of Beverly City, and 19-year old Alexa Hess of Burlington City.

There was then an argument inside the vehicle and Janson tried to get out of the vehicle.

When he attempted, Crowderparham shot Janson.

Hess, who was behind the wheel, then drove away with Crowderparham to a residence nearby so they could clean the vehicle.
