Lajah Richardson’s fiancé, Deputy Darrel Garrett, is one of three officers who were "ambushed" and shot from behind in Houston. Officials are still searching for the suspect.

Deputy Kareem Atkins was killed in the shooting and leaves behind a wife and two children. Deputies Jaquim Barthen and Garrett were shot and wounded.

Richardson described the three men as "brothers."

"They all met when they all joined the force, but you would think that they've been friends way before then," she said on "Fox & Friends."

"All three of them came through for each other. Even it if was for me or for Atkins’ wife or for Barthen’s girlfriend," she said. "We were a family."

Deputy Garrett is still recovering from his injuries. Richardson is hopeful but said her fiancé’s health is still a concern.

"He's making it," she said. "I don't want to say he's doing OK because he's not doing OK. He just had surgery yesterday again. That was his third surgery."

Richardson was aware of the danger police officers face. She said she discussed it with her fiancé often and he was trained for situations like this. 

Nevertheless, she said she’ll never forget the phone call she received.

"They called me at 2:23 a.m.," she said. "When my phone rang and it wasn’t Darrell, I knew something was wrong." 

Richardson said Deputy Atkins had recently purchased a home with his wife. She said the couple was excited to start a new chapter in their lives together. 

"I’m really just devastated," she said. "I just can’t stop the tears."
