Donald Cox

Donald Cox Jr. has been identified as the lead suspect in the July 26, 1989 murder of 16-year-old Fawn Cox in Kansas City, Missouri. The case has been cleared by exception due to the death of Cox. Fawn was assaulted by an intruder in her bedroom after coming home from work on the night of July 26, 1989. She had been sexually assaulted and strangled. Her body was found by her mother and sister the next morning when they went to wake her up.

The FGG investigation was conducted by Parabon Nanolabs. The Cox family raised the money for the FGG and advanced DNA testing. The suspect was found to be Fawn’s cousin, Donald Fox Jr. He died of a drug overdose several years ago.

Three teenagers were initially charged with the crime, but the charges were dropped due to a lack of evidence.
