The West Babylon High School alum was a standout star in his high school days and went on to play for the NFL's Kansas City Chiefs as a starting defensive back.
ESPN reports his family requested that Belcher's body be exhumed for testing on his brain to provide an explanation of the events that unfolded last December. Belcher's body was exhumed from a Bay Shore cemetery on Friday, according to multiple reports.
Brain tests nearly a year following the suicide, according to medical sources, might not provide accurate results.
Belcher committed suicide at the stadium in front of two Chiefs officials last December. He had already shot his girlfriend, the mother of his child, inside of their home earlier that morning following an argument.
"We can confirm that there was an incident at Arrowhead earlier this morning," the Kansas City Chiefs said in a statement on the day of the tragedy.. "We are cooperating with authorities in their investigation." Arrowhead Stadium continues to remain on lockdown.
Belcher and his girlfriend, Kasandra Perkins, 22, had a child earlier this year, according to Deadspin.
Belcher was a standout player during his time at West Babylon Senior High School, leading the team to a perfect season in his senior year. He played linebacker, offensive tackle, nose guard and fullback while on the varsity team. He graduated from the high school in 2005.
Belcher also attended the University of Maine, where he graduated in 2009 with a degree in Child Development, according to the Chiefs' media guide.
