The people stepped up to help solve a deadly crime.
Trooper Johnna Batiste of Washington State Police needed some help catching a hit-and-run driver.
So she sent out a picture of a car part. The mystery part was part of the crime scene and believed to be a link to the unidentified driver suspected of killing a cyclist. Batiste also included a photo of the destroyed bike.
After the tweet found it's way to Reddit to a sub-category "What Is This Thing", is when a user JeffNuts, a former Maryland state inspector was able to identify the part at part of the headlamp from 1988 Chevrolet Silverado truck.
Shockingly, a few days later Trooper Batiste posted again that because of the tip, they had arrested the suspect.
People were feeling pretty proud of the internet.
With a special shout out going to the man himself.
Citizen team work for the win.
