http://deadspin.com/5964841/report-...actice-facility-and-killed-himself-[updating] Police are investigating two deadly shootings Saturday morning that they said are related. The shootings involve a Chiefs player and his girlfriend. The first shooting was reported about 8 a.m. at a home near 54th Street and Chrysler Avenue. The second shooting was reported a short time later at a Chiefs practice facility located on the Arrowhead facility. Officials said the Chiefs player shot and killed his girlfriend and then drove to the practice facility where he shot and killed himself. It's unknown if people were at Arrowhead or any of its surrounding facilities at the time. Twitter rumors are flying about who the player is—observers of varying levels of access seem to have settled on a single candidate—but we'll wait to confirm, and will update this post as more information becomes available. Update, 11:04 a.m.: It looks like the original guesses were correct: CBS's Jason La Canfora is reporting the player in question was Javon Belcher.
