Let’s state this at the outset: none of the news reports of Sunday morning’s Essex, Maryland home invasion mention what caliber the bad guys were using. Why is that important? “According to investigators, two armed men broke into the apartment and shot 24-year-old Kenneth David Cox several times.” But Cox is obviously the resilient type. Though wounded and apparently without a firearm, “Cox then grabbed a blunt object and struck the alleged shooter in the head, killing him. At that point, police say the second suspect fled the scene.” The good news is that Cox is reported to be in serious but stable condition. Neither this report, nor one at baltimoresun.com IDs the gun – or the blunt object – used. The dood who took off running into the night is still, as they say, at large. Let the caliber speculation commence.
