As my actual family and my Kansas City Chiefs family have been altered forever, we ask that you keep us and most importantly their child in prayer. Thank you all for your continued support."

Recently, police released 911 recordings from that night they found Perkins with multiple gun shot wounds to her chest and one through her neck, while another recording could be heard of police with Belcher, while his coach and general manager desperately tried to negotiate with the athlete to put his gun down.
