Jan. 2 (UPI) -- Gordon's brother Jack Walker Jr. confirmed to People magazine that his sibling died Wednesday in Florida from a drug overdose.
"We are devastated by the loss of my beautiful brother," Walker Jr. said in a statement. "He leaves a void in the hearts of my family and his friends. Nick's battle in life was not an easy one. I will be forever grateful that my God afforded a small moment at the very end of Nick's life, and I was able to hold his hand as he journeyed on."
Gordon's attorney Joe Habachy also confirmed his death in an email to The Los Angeles Times. "He worked hard to hold his head up and stay sober," Habachy said.
"He genuinely wanted a happy healthy life with his family more than anything else. My heart goes out to the family and friends Nick leaves behind and to other families dealing with the losses and heartaches caused by drugs," he continued.
An autopsy indicated that her death was caused by complications related to drugs and immersion in water. Houston died at the age of 48 in February 2012 after accidentally drowning in a bathtub while intoxicated.
Gordon was found liable in the wrongful death case of Bobbi Kristina Brown and was ordered by a judge to pay $36 million to her family.
