On the morning of June 23, 2023, gunfire erupted inside a home on Fort Monroe Court in Dumfries, Virginia, after an argument among several people in the residence. Prince William County officers arrived at 9:42 a.m. and found 21-year-old Jeremiah Quentin Deck and a 23-year-old man suffering from gunshot wounds to their upper bodies. First aid was given at the scene and both were taken to a nearby hospital; Deck later died of his injuries and the other man was hospitalized with serious wounds.

Investigators say one man went to the home’s upper level and opened fire, then fled in a blue 2006 Ford Explorer. Police identified 33-year-old Daniel Christopher Shannon of Fredericksburg as a suspect, issued a warrant and publicized his description and vehicle. On June 27 Shannon turned himself in and was charged with one count of murder in Deck’s death, one count of aggravated malicious wounding for the second victim, two counts of using a firearm in the commission of a felony, and one count of discharging a firearm within a dwelling; he was held without bail pending court.

If anyone in Dumfries or Fredericksburg saw the blue 2006 Ford Explorer around June 23 or has information about the events at the Fort Monroe Court residence, please come forward.
