"We may not understand the reasons why we are here or understand what caused this tragedy," said Pastor Dawn Mixon to several hundred people there to remember the 25 year-old whose life ended in tragedy.
On Dec. 1, Belcher murdered his girlfriend, Kasandra Perkins, then drove to the Chiefs' practice facility where he took his own life in front of Chiefs officials, including head coach Romeo Crennel.
Wednesday, relatives wore black and red as mourners viewed a photo slideshow commemorating Belcher's life, which showed pictures of his childhood and of playing football in high school and at the University of Maine.
The slideshow also showed pictures of Perkins with their three-month-old daughter Zoey, with words that asked those in attendance to "Keep this little girl in your prayers."
A memorial service was held last week in Kansas City for Chiefs players and staff.
