Loved ones said the three men had a bond like brothers.
"They did everything together," said Lajah Richardson, the fiancée of 28-year-old Deputy Darryl Garrett.
She said she has not told Garrett that his best friend was killed because she does not want the terrible news to jeopardize his recovery. Garrett was shot in the back multiple times and had undergone surgery on Sunday.

Funeral arrangements have not yet been announced.
