KCTV5 news is reporting two deadly shootings that are connected. Kansas City Chiefs linebacker Jovan Belcher shot his girlfriend at one location and then himself at the Arrowhead practice facility, according to Kevin Kietzman of Sports Radio 810.
According to the report, Belcher shot and killed his girlfriend and then drove to the practice facility where he shot and killed himself.
The first shooting occurred at 54th Street and Chrysler Avenue, which is 11 minutes away from Arrowhead Stadium. The first shooting happened at 8 a.m. The second shooting happened shortly afterward at Arrowhead Stadium's practice facility.
Arrowhead security has also placed the practice facility on lockdown.
It's hard to imagine what the players are going through with a game set for kickoff in 26 hours from when the news broke. The Chiefs will host the Carolina Panthers tomorrow at Arrowhead Stadium. Panthers interim general manager Brandon Beane was told by the league to continue travel plans as scheduled.
The saddest part about this story is that Belcher and his girlfriend had a baby less than three months ago.
Our thoughts and prayers go out to the Chiefs organization and family members who lost a loved one in this shooting.
