Corey Thompson was killed on the porch of a Sanford Street residence in Muskegon, Michigan, during the early hours of July 4, 2017. He was 44, Black, and a father of seven. The shooting followed a dispute the previous evening in which Thompson and his brother had an altercation with a man named Kahlek McPherson and two others; that confrontation reportedly left lingering resentment.

Investigators linked McPherson to the killing; he was charged with open murder, felony firearm, and being a felon in possession of a firearm. At trial a jury found McPherson guilty of first-degree murder, and as the verdict was read he made an outburst in court admitting the killing. McPherson was sentenced to life in prison without the possibility of parole.

Does anyone have information about the July 3 altercation or who accompanied McPherson that night?
