These are the victims of the Dallas, US police shootings

The five officers killed by a sniper during a protest in Dallas have been named. They included Dallas Area Rapid Transit (DART) officer Brent Thompson and Dallas Police Department officers Lorne Ahrens, Michael Smith, Patrick Zamarripa, and Michael Krol.

Brent Thompson was 43. He had just married a fellow officer two weeks ago, and he had six children.

On his Linkedin profile he says "I enjoy working on challenging tasks and problem solving with my peers. I am constantly looking for different ways to serve the department, this helps to keep my work from becoming sedentary and boring."

Dallas Police Officer Patrick Zamarripa, 32, had completed three tours in Iraq with the US Navy. He leaves behind a daughter and a stepson.

On his Twitter account he described himself as "addicted to the thrill of this job. I own the night. I love my Country, Texas, Family, God, Friends, and Sports! Don't Tread on Me! 'Merica."

Dallas Police officer Michael Krol had been in the department for eight years. He was following his life-long dream by being a police officer.

Dallas Police Sgt. Michael Smith, 55, was formerly an Army Ranger, and he had two young children and a wife of 17 years. He had been awarded the "Cops' Cop" award from the Dallas Police Association.

Dallas Police officer Lorne Ahrens was a 14-year veteran of the Dallas Police. He was a former semi-pro football player, and is survived by his wife, two children and a step-child.

DART released the names of the other three of its officers injured in the shootings: Omar Cannon, Misty McBride, and Jesus Retana.

"As you can imagine, our hearts are broken. This is something that touches every part of our organization. We have received countless expressions of support and sympathy from around the world through the evening. We are grateful for every message. Thank you," DART said in a statement.

"We are grateful to report the three other Dart police officers shot during the protest are expected to recover from their injuries. No other Dart employees working in Downtown during the protest or shooting were injured. We also extend our sympathies to our colleagues at the Dallas Police Department in the loss of their five officers."
