At his wake Tuesday, fellow Marines from his unit remembered Hendricks as a great guy.

“It would be a horrible situation, and he could make you laugh – going through training, stuff like that. He’s just one of the greatest guys we have, honestly,” Sgt. Craig Hollis said.

“He was always ready to go and a good guy,” added Cpl. Sandy Taveras. 

Hendricks celebrated his 25th birthday last month and was expected to return home in a few weeks, his mother told CBS2. His younger brother, who followed him into service, escorted his remains back to Locust Valley.
