A Waikato police officer has shared an emotional post on social media about the effects of witnessing the aftermath of a fatal crash.
The police officer, who has remained anonymous, says they are struggling to sleep after delivering the devastating news to a father that his daughter had died in a car crash on Tuesday.
The crash, near Matamata, saw a woman lose her life while her husband and children were taken to hospital after surviving the wreck.
The woman's father and mother had been travelling in a vehicle in front of them and heard the crash.
"I've been in the police for nearly 20 years now. In that time I have attended lots of accidents, with a fair few being fatalities," the officer said in the post, which was shared on the Waikato Police Facebook page on Thursday.
"It was just another and I emotionally went into that space that I go to when I attend. I don't do tears and I don't do emotion. I switch off and go into professional mode. Arrive, assess the scene, quickly speak to witnesses, check to see who is injured, what resources are needed, more witnesses, preserve evidence and so on.
"The victim's body was still in the car upside down in the ditch, the injured were now in the two ambulances that attended and we were waiting for the air ambulance helicopters to arrive."
The officer said they try to keep emotion at bay, but found it hard when the woman's father asked if his daughter had died.
"I don't do tears and I don't do emotion.... up until that point. I think I mumbled - yes she is," the officer said.
"To be confronted by a dad who has lost his daughter, a husband who has lost his wife, and two kiddies who have lost their mum, it just brought the tragedy home."
The police officer wasn't sure what would be achieved by sharing the post, but wanted to let people know that "the emergency services have to deal with this sort of thing regularly".
"Each of us are affected and deal with what we see in our own way."
The officer wrote the post just after 3am, stating that trying to sleep was an issue after dealing with a tragic fatality.
