Teresa E. Kellough, 49, was found fatally shot in her Kansas City, Missouri, home on a Tuesday morning in September 2014 after she failed to show up for her shift at Pete and Mac’s Pet Resort. A co-worker who went to check on her discovered her body in the 4200 block of Forest Avenue. Investigators recovered five spent bullets, four 9 mm shell casings, and one live 9 mm round at the scene.

Forensic testing on the unfired round produced a DNA profile that matched Nathaniel E. Brown, then 29, who had a prior conviction for first-degree robbery. Brown had a connection to the house: his mother had formerly owned the residence, and Kellough had shown him the home in May 2014. Cell phone records and text messages confirmed communication between them. In November 2014 federal prosecutors charged Brown with being a felon in possession of ammunition; in December 2014 the Jackson County Prosecutor’s Office charged him with first-degree murder and armed criminal action. The DNA on the live round is the central piece of evidence described in the case file.

Does anyone have information about Brown, the house on Forest Avenue, or contacts who knew Teresa in 2014?
