He graduated from East Carolina University in 2003 with a bachelors in communication and a minor in business administration.
His mother, Corliss, told Inside Edition: "This is any parent's worst nightmare. It is horrific. I will never get over this in my whole life. Never ever. We all know we gotta go but in such a horrific way is just… What do you say to that? To know that your son got shot up for going to a dance club?”
She emotionally added: "I will never see my son again because of it…He took my son’s life and 40 something others for his mental illness."
Six of his closest friends eulogized their friend to Inside Edition.
Koren Green was the last to see Tomlinson. She watched him perform at Blue Martini earlier in the night.

Jai Saint, added: "It was positive energy all the time."
Saint said he and friends would frequent Pulse "once a month," but they did not accompany him on the night of the shooting. Each of his buddies had other engagements.
