Hearts are broken across the metro after a head-on collision Friday morning near Northwest Expressway and Sara Road.

It’s not clear why, but Oklahoma City police reported a Canadian County lieutenant crossed the center line, and hit a minivan with two people inside around 9:30 a.m.

Lt. Shirley Lanning was driving the unmarked cruiser and died at the hospital.

The victims inside the minivan were also taken to a local hospital with non-life-threatening injuries and were stable at last check.

Word of Lanning’s passing traveled fast.

She served in law enforcement for decades including: the Oklahoma County Sheriff’s Office, University of Central Oklahoma, and for the past six years at the Canadian County Sheriff’s Office.

“It was tough to lose not just a good deputy, but a great friend,” said Captain Adam Flowers.

“I met her when I was a trooper back in the mid-80s, and she was a jailer at the Oklahoma County Sheriff's Office. I remember going in, I'd be going in there to take somebody, book them in and Shirley was just, she was the same then. She was a pistol,” said Canadian County Sheriff Chris West.

She's survived by her parents and husband. The sheriff said the Lanning’s lived in Edmond.

Now, her service-photograph will hang in the halls of the sheriff's office for years to come.

“She'll always be in the department. She's part of our family and just because she's not with us here on earth anymore, I mean she's with us in spirit,” said Flowers.

The Canadian County Sheriff’s Office also reached out to the two others who Lanning allegedly hit.

“They were in the hospital, in the emergency room… a few rooms down and myself and the undersheriff had a chance to visit with them. We want them to be in our prayerful thoughts,” said West.

The Oklahoma City Police Department is still investigating the crash.

The Canadian County sheriff said he was unaware of any existing medical issues involving the deputy.
