All five of those killed Thursday night at the Dallas protest were law enforcement officers — four of whom served with the Dallas Police Department, while a fifth worked for Dallas Area Rapid Transit, or DART. That DART officer has been identified by the department as Brent Thompson.
"Dallas officers are hurting," Dallas Police Chief David Brown said on Friday morning. "We are heartbroken. There are no words to describe the atrocity that occurred to our city. All I know is that this must stop, this divisiveness between our police and our citizens."
Here are the names of those who lost their lives in the Dallas shooting — and their stories.
Brent Thompson, 43
"Officer Thompson is the first officer killed in the line of duty since DART formed a police department in 1989," the agency writes in a statement. "He joined the DART Police Department in 2009."
Prior to his service with the agency, Thompson had worked with DynCorp International, supporting the operations of American police officers who were training Iraqi law enforcement in southern Iraq, according to Thompson's LinkedIn profile.
Thompson had gotten married in the past two weeks, DART Police Chief James Spiller told CNN's morning program New Day on Friday.
"He was in great spirits from his recent marriage," Spiller said.
DART Executive Director Gary Thomas, also speaking to CNN, spoke of Thompson's international service.
"He was a dedicated officer," Thomas said, "dedicated to the safety of Americans, all over the world certainly."
Patrick Zamarripa, 32
In a Facebook post Thursday night, his father, Rick, explained the circumstances of his son's death:
Most of you already know this by now today in Dallas , my son is a police officer in Dallas he was working there the rally in downtown where my son was shot and killed by a sniper along with four other police officers maybe more at this moment I'm still at the hospital here in Parkland Hospital to see him be moved to the medical examiner's office."
Rick Zamarripa added: "need prayers to get through this."
In an interview with The Washington Post, the elder Zamarripa elaborated. When news of violence in downtown Dallas broke Thursday night, he told the paper, he sent a text to his son asking whether everything was OK. Rick Zamarripa told the Post it was unusual to be met with silence on the other end.
It wasn't until he arrived at the hospital later that night that Rick Zamarripa's fears were confirmed.
The officer he met at the hospital "wouldn't tell me," Rick told the Post. "He had that look on his face. I knew."
In a tweet posted Thursday night, Zamarripa's stepbrother Dylan Martinez added: "Family man and military veteran. Just not right."
Zamarripa served in the U.S. Navy in both Iraq and Bahrain. The Post also reports that Zamarripa had a young daughter.
Michael Krol, 40
"He wanted to do more, that's kind of how he was. He wanted to make everything better," Krol's uncle Jim Ehlke told WDIV Detroit. "It was probably the most frustrating thing for him — he couldn't solve it all."
Michael Krol served with the jail system in Wayne County, Mich., before heading to Dallas to pursue a career as a police officer there, according to Detroit local media.
"We are saddened by the loss of the dedicated officers in Dallas — one of whom was a former member of this agency — and also the wounding of the other officers," Wayne County Sheriff Benny Napoleon said in a statement Friday morning. "Those officers made the ultimate sacrifice and died honoring their oaths to protect and serve. Our thoughts and prayers go out to their families and also the Dallas Police Department."
"He got into law enforcement and worked really hard to be a police officer," Ehlke told Click On Detroit. "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."
It was a gamble for Krol, The Washington Post reports. His brother-in-law Brian Schoenbaechler told the paper he left his family and familiar surroundings for Dallas for a very simple reason: "He said, 'This is something that I wanted to do.' "
To Click On Detroit, Ehlke added: "He was all in, he was all in."
