Alexander and his brother Chris were at a party in Southwest Miami-Dade when they were jumped by a group of men. A verbal altercation became physical. Alexander suffered multiple stab wounds to his torso. His brother suffered cuts to his head and hand before he was able to break free.

"He was the most selfless guy you never meet and he would teach me to be like him," Chris said.

Alexander, a nuclear engineer, is remembered as a kindhearted, positive, fun-loving man.
