The U.S. Park Police are seeking a gold or tan Ford Explorer that apparently was taken from a person who was killed on Tuesday on the grounds of the Beltsville Agricultural Research Center, according to authorities.

Police released few details but said the incident occurred near Springfield and Powder Mill roads, which cross fields at the sprawling center in Prince George’s County. Police did not say whether the victim was male or female, and what time and how the death occurred.

Police described the vehicle as a 1996 Ford Explorer XL. They also said that the victim used several different license plates and the ones that were on the vehicle when it was taken are not known.

Police said that the occupants of the vehicle “should be considered armed and dangerous.” Anyone with information is urged to call the U.S. Park Police at 202-610-7515.
