Brent Thompson
Thompson, 43, a nearly seven-year veteran of the transit force, got married in the last two weeks, Spiller said. His spouse was a fellow transit officer. Thompson also served as a police training officer in Iraq and Afghanistan.
Patrick Zamarripa
Zamarripa was a U.S. Navy veteran who was deployed to Bahrain as part of the Iraq War effort, military records show.
He was the father of two children and greatly loved by his own father, Rick Zamarripa.
"He was very giving," Rick Zanmarripa told CNN. "He would give you his last dollar if he had it in his pocket and you needed it. He would bend over backward to help anybody out. He was very patient and he would try to help anybody out the best he could.
Michael Krol
Michael Krol's lifelong dream was to be a police officer, his uncle, Jim Ehlke, told CNN affiliate WDIV.
"He got into law enforcement and worked really hard to be a police officer. He spent some time at the correctional facility. It wasn't quite what he was looking for, so he worked pretty hard to find a job and got one in Dallas," Ehlke said.
Krol worked with the Wayne County Sheriff's Office from 2003 to 2007.
Lorne Ahrens
Dallas Officer Lorne Ahrens was a great co-worker, said Sgt. Anthony Gunn of the Los Angeles County Sheriff's Department.
"I had the honor of working with Lorne at LASD's Lennox Station in the early 1990s and at Lancaster Station in the late 1990's," Gunn told CNN. "I was a young deputy and he was a law enforcement technician, assigned to input and dispatch calls for service at both stations.
"He was the kind of guy that it made you happy when you got to work and saw he would be working the shift with you. You could count on him to do the right thing, the right way. He was a dedicated professional. He was well-grounded, seeing the world the way it really, is but not letting the evil in the world discourage him from doing good."
Michael Smith
Dallas police Officer Michael Smith was among the dead, according to CNN affiliate KFDM and local media reports. Smith joined the department in 1989, his sister told CNN affiliate KFDM.
