Mook (graffiti artist)
Mook is the graffiti moniker used by an American man Michael Monack, who was active in graffiti vandalism in Pittsburgh in the early 2000s. The name means "knucklehead or idiot.". A copycat graffiti vandal named Marcus Edward Gunther in Portland Oregon who subsequently tagged with the MOOK moniker was ultimately sentenced to two years in prison in February 2019 for repeated graffiti vandalism in the late 2010s.
Monack began as a tagger targeting the South Side and Shadyside neighborhoods, but after his tags were abated, he began placing his tags in hard to reach places, including tall bridges and highway overpasses. He drew the ire of the then-Pittsburgh Mayor Thomas J. Murphy, Jr., who had tried to provide an outlet for individuals interested in graffiti to use the walls along the Eliza Furnace trail. He has etched "Mook" onto a Department of Public Works "Graffiti Busters" truck that was tasked with cleaning up graffiti. At one point, merchants from the South Side, tired of having their businesses targeted confronted Monack. He tagged "So you want to get tough?" on the Birmingham Bridge. in response.
He became known around the community for vandalizing previously unheard of places. According to Pittsburgh officials, "He's going into areas no one's gone before." He became known among law enforcement across Pennsylvania. After the media coverage of Monack's "Mook" tagging in the Pittsburgh area, it is possible that multiple copycats have applied graffiti using the moniker "Mook". As Monack received more coverage for his daredevil mischief, he gained more opponents as well as supporters. One of his supporters described him as "determined and skilled and has a sense of humor," commenting that "Although Mook has committed a crime, everyone loves him and he makes people happy." Others objected to the public praise and commented his supporters should help clean up his graffiti.
On November 1, 2001, after receiving anonymous tip letters, police arrested 18-year-old South Side resident Michael Monack. He was found with graffiti supplies. In October 2002, Monack was sentenced to thousands of dollars in fines and community service in exchange for his guilty plea to criminal mischief and defiant trespass. On March 2003, police arrested Monack again for continuing to engage in graffiti. Monack had been spotted in the Armstrong Tunnel at 5AM with two juvenile delinquents. He attempted to escape apprehension and fled to the South Tenth Street Bridge where he was arrested. Monack was charged with criminal mischief, conspiracy, possessing an instrument of a crime and corruption of a minor for being the group's "ringleader." His hearings were attended by neighborhood activists from areas targeted by his tagging where they expressed their extreme displeasure at his behavior.
As of 2004, Monack had become a tattoo artist in Pittsburgh. When asked by the Pittsburgh Tribune-Review about his opinion on the latest crop of the city's graffiti artists, he described them as "garbage." Though, even years after ceasing his tagging, Mook's "infamy precedes him in many circles of the city." By 2008, Monack was described as having been replaced in local urban folklore by a now deceased graffiti tagger Daniel Montano whose moniker is MFONE.

Oregon Department of Transportation and the Portland Police Bureau began investigating after graffiti appeared on two sets of brand new electronic signs hanging over I-84 freeway in Portland before they have been commissioned. One of the sets was tagged with the moniker "Mook" on June 29th, 2018. The damage was nearly $25,000. On September 13th, 2018, a Portland man Marcus Edward Gunther was arrested. A security video footage from a different "MOOK" graffiti incident on September 6, 2018 at a storage facility linked Gunther to the moniker. According to police, Gunther was lodged at the Multnomah County Jail on charges of Criminal Mischief in the Second Degree (two counts), Criminal Mischief in the First Degree, and a probation violation. Gunther also has pending matters from Clackamas County and Washington County.  The Columbian reports that Gunther's graffii tags have also been found in the nearby city of Vancouver, Washington.
