TUCSON, Ariz. - People who join the dangerous world of law enforcement see each other as brothers and sisters where ever they serve.
Members of law enforcement -- and civilians -- reach out when one of their own is killed.
Thursday, officers draped a giant badge in black at Tucson Police Headquarters, in remembrance of DPS Trooper Tyler Edenhofer, killed in Phoenix Wednesday night, but also to remember Tucson Officer William Katzenstein, ambushed and killed exactly 116 years ago.
Tucson Police Chief Christopher Magnus says, “I think anyone or our men and women who goes out to do police work faces some incredible dangers. And even though we do the best we can with training and supervision and equipment, we're still up against an unknown when you go out there."
Members of TPD, and other agencies in the brotherhood of law enforcement reached out right away with messages of solidarity, sympathy and grief.
On Twitter, the Pima Sheriff's Department wrote, "We are deeply saddened by the loss of Trooper Tyler Edenhofer."
The Santa Cruz County Sheriff’s Department tweeted, "Our thoughts, prayers and condolences are with the Edenhofer family and the Arizona Department of Public Safety.
Chief Magnus says, “So we have already reached out to the Department of Public Safety and willingness to help them in any way we can, with any sort of resources or support they might need."
Officers will come from all over the country to attend a fellow officer's funeral. Civilians will often line the streets to pay their respects too.
On the KGUN9 Facebook page Alfonso Lares said in part, "I am a Vietnam War veteran. It hurts me deeply when I hear someone killed in any law enforcement agency."
TPD Captain James Scott said of Trooper Edenhofer. "He will not be forgotten, nor will we be discouraged as we continue to serve all."
