PARAMUS – When her car developed a flat tire on Route 4 Sunday, Kimberly Garcia didn’t call AAA. Instead, she pulled over and did the dirty job of changing the tire herself.

Somewhere during the process, however, she lost her diamond engagement ring.

“When she returned home she realized that her ring was missing and called our department to file a report,” Paramus police said in a statement posted to Facebook Tuesday.

Garcia, 27, went back to the highway, where she and police officers searched for the ring.

The initial search turned up nothing, police said.

Determined not to give up, one of the officers returned to Route 4 during his free time.

“The next day, (Officer Jon) Henderson spent his free patrol time scouring the area where she had been,” police said.

Henderson found the ring in the road and returned it to Garcia.

Tamira Mobley of Wood-Ridge pleaded guilty to manslaughter and other charges in a cosmetic-injection death.

Police on Tuesday posted a photo to the department’s Facebook page a photo of Henderson with a smiling Garcia – who displayed the ring on her finger.

“The Paramus Police Department is ecstatic that Officer Jon Henderson was able to recover the lost engagement ring of Kimberly Garcia,” police said.

Garcia’s wedding is planned for August 2018.
