Authorities are looking for the driver of the green Ford Expedition that killed a 29-year-old police officer and Iraq war veteran in Phoenix, Ariz., on Sunday, AZfamily.com reported.
Officer Daryl Raetz was on scene investigating a driving-under-the-influence incident when someone behind the wheel of an SUV hit him and kept going.
"This is a tragic day for the city of Phoenix," Sgt. Tommy Thompson of the Phoenix Police Department said in a news conference Sunday.
Phoenix Police Chief Daniel Garcia called Raetz "one of Phoenix's finest. One of our heroes."
"I honestly don't have the words to describe the sorrow in my heart for Daryl Raetz and his family," Garcia said.
Raetz had served the police department for six years after working as a military medic in Iraq.
As the Arizona Republic reported, Raetz died on the same day as a local firefighter, Brad Harper, who was crushed between two vehicles while fighting a fire.
“No words of mine can ease sorrow this deep for the family and friends of these two men, nor the brothers and sisters in uniform who served alongside them,” Arizona Gov. Jan Brewer said of the deaths.
