A former resident of Redford Township, a suburb of Detroit, Krol worked as a Wayne County Sheriff's Deputy in the county jail system from 2003 to 2007. He moved to Dallas in 2007 to join the city's police department.

Krol's uncle, Jim Ehlke, told local TV station WDIV, that his family worried about him, but also knew that policing was his passion. "He got into law enforcement and worked really hard to be a police officer," Ehlke said. "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. He was all in, he was all in."

Krol's mother, Susan Ehlke, told local TV station WXYZ that her son was a very "caring person." "He was living a dream of being a police officer," she said. "(He) Just turned 40 in April. He knew the danger of the job but he never shied away from his duty as a police officer," she added. "He ... wanted to help people."

Paying tribute to Krol, Sheriff Beny Napoleon said in a statement: "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. 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."

Krol, who had a long-term girlfriend was not married and had no children.

The first officer identified, who was killed in the shooting was Dallas Area Rapid Transit officer Brent Thompson.

Of the 12 officers shot, some were from DPD and others with DART police. The attacks made Thursday the deadliest day for U.S. law officers since the Sept. 11, 2001, terrorist attacks, according to The National Law Enforcement Officers Memorial Fund, which tracks on-duty deaths. Decrying the killings President Obama said that 'justice will be done and those involed will be held fully accountable.'
