In the spring of 2015 a double homicide in Dickson, Tennessee, ended the lives of Lisa Wade MacKenzie Mickey McDonald, 23, and her 27-year-old boyfriend John Chris Goldtrap. Firefighters discovered both bodies and a fire at the duplex on McFarland Lane on April 14, 2015; investigators say the blaze had been set intentionally to conceal the primary crime. Both victims had been shot in the head.

Investigators focused on Kenneth Ray Niles, described as a cousin by marriage to Goldtrap. Niles was reported to have been at the home the night of April 13 and to have argued with Goldtrap over pills both men reportedly sold. Authorities say evidence included inconsistencies in Niles’s statements and text messages between him and Goldtrap suggesting a drug-related motive. Police also allege Niles stole items from the home and returned the next morning to set the fire.

A grand jury later indicted Niles on multiple counts including first degree murder, felony murder, aggravated arson, especially aggravated robbery, especially aggravated burglary, and theft over $1,000. Two other men, Jamey Earl Donegan and Joshua Michael Pickering, were separately indicted on charges of fabricating evidence amid allegations Donegan offered to kill the person responsible and Pickering posed as the killer. Lisa McDonald is remembered as a loving mother and a pathology assistant with a bright smile.

If anyone knew Lisa, Chris, their routines, or saw suspicious activity near McFarland Lane on April 13–14, what can be shared with investigators?
