Chung Kim, Texas Man, Allegedly Kills 2 Neighbors Over Dog Feces Argument (VIDEO)

An argument over dog feces led to the fatal shooting of a Dallas couple, authorities told local reporters.

Chung Kim, 75, allegedly shot neighbors Jamie Stafford and Michelle Jackson, who lived in the apartment above his, after a dispute about the couple dumping their dog's feces onto Kim's patio erupted Monday morning, the Dallas Morning News reports.

According to neighbors in the Sable Ridge apartment complex, the feud between Kim and the couple raged on for about a year, CBS Dallas-Fort Worth News reports. They told the station the fights revolved around noise and the pit bull's bathroom habits, both of which Kim often complained to management about.

However, the ongoing argument came to a head Monday, when Kim allegedly shot Jackson from his patio below, then proceeded upstairs and entered the couple's apartment to fatally shoot Stafford, who was trying to escape over the balcony.

From the Star-Telegram:

Stafford dropped to the ground, but Kim stood over him and shot again, killing him, police said in the affidavit.

Stafford and Jackson were reported dead on site. The pair had five children.

Kim, who was taken into custody by police after he tried to flee the scene, is facing charges of capital murder, the Morning News reports. In Texas, capital murder typically carries a sentence of life in prison without parole, or the death penalty.

Dog poop was also the subject of an argument that incited a February 2012 murder in Philadelphia, when a man allegedly pulled a handgun on a neighbor who complained about droppings in his yard.
