"He had a very positive attitude and a positive perspective on life and how to live life to the fullest," she said. "That was Evan's motto. Every day, he lived life to the fullest.
"Everybody loved him. Evan didn't have any enemies," Curry said.
They last hung out earlier this month at the annual City-Poly football game. When Curry texted Curbeam before the game to ask if he was ready, Curbeam responded with pictures of his old Poly baseball jersey and letterman's jacket, fresh from the cleaners.
"He was beyond ready," Curry said.
Sian Williams also kept up with Curbeam after high school. They met in the marching band, where Curbeam played on the drum line and Williams was in the flag and poms group. "He was always talking, really goofy, really social," Williams said.
Williams and Curbeam video-chatted while he was at basic training and talked more often when he returned to Baltimore. The last time they saw each other was at the City-Poly game.
"The Poly family is pretty tight, even with different classes," Williams said. "When you lose one, it hurts everybody."
Funeral services for Curbeam will be private, his family said.
