On the morning of Sunday, April 22, 2018, officers in Saint Louis were sent to a residence in the Walnut Park East neighborhood after reports of a shooting. At about 7:00 a.m. they entered a home in the 5200 block of Gilmore Avenue and found a man with apparent gunshot wounds. First responders pronounced him dead at the scene.

The victim was identified the next day as 54-year-old Mark Jacox, a local resident. His death was recorded as the city’s 46th homicide of 2018. The St. Louis Metropolitan Police Department opened a homicide investigation, canvassed the area for witnesses and evidence, and asked anyone with information to contact CrimeStoppers.
