Following months of investigation, police have arrested a man who carved a QAnon hashtag into a 4,000-year old stone landmark in New Hampshire.

According to Patch, police were first alerted about the vandalism at America's Stonehenge on Haverhill Road in Salem, New Hampshire when it was reported in September 2019.

When the police arrived, the site owner explained the vandal left "an unusual wooden cross with several pictures and drawings, suspended from two trees," which suggested execution of the people in the photos by crucifixion.

In addition, the perpetrator had also used a power tool to carve "WWG1WGA" and ''IAMMARK" into the site's main tablet, a detail police found puzzling at the time.

But over the course of the investigation, people began to come forward with connections between the cross, the messages and posts made by a specific Twitter account, which has since been deleted.

The account, named "iammark," had posted some content including the site and the same photos found on the cross.

And then one Tweet in particular hammered home his guilt.

"Do you see any reason not to take down their portals? Boston specifically oh and the 66 Baal shaft? Oh made a few improvements @American Stonehenge (crying emoji) sorry Scottie Wolters my bad (middle finger emoji)."

Investigators also learned that "WWG1WGA" is an acronym used by many online QAnon believers, meaning "Where We Go 1, We Go All."

Eventually, police linked the Twitter account to Mark Russo, a 50-old-man in New Jersey. He was arrested on March 1 and later released on $3,000 bail.

People who heard about the story on Facebook were left with little to do but shake their heads.

Much like the events at the Capitol on January 6, this guy used the internet to make it easy for the police to eventually line up all the evidence they needed.
