Nick's brother, Jack Walker Jr., shared the news Wednesday by writing, "GOD WHY I DID I HAVE TO LOSE MY BROTHER ON NEW YEARS," and adding ... "All I can do is cry." He later shared a tribute post with several photos of himself with Nick.
It appears Gordon was hospitalized for a short time before his death ... Walker says he was at his brother's bedside and spoke to him in his final moments. Reports say Gordon died of a suspected drug overdose.
As you'll recall ... Gordon and a friend found Whitney Houston and Bobby Brown's daughter face down in a bathtub on January 31, 2015, and she was placed in an induced coma. Brown suffered irreversible brain damage and remained unresponsive, and passed away in hospice care on July 26, 2015.
We're told Gordon had moved to Orlando a few months ago.
He was 30.
