They repeatedly tagged the scoreboard and baseball dugouts at Fife High School, the city pool, Chamber of Commerce and various businesses.
After three months of trying to identify the taggers, police on Monday arrested an 18-year-old man and 14-year-old boy believed to have spray painted graffiti at 22 locations since early November.
“It cost thousands of dollars in damage at least,” Lt. Tom Thompson said.
The case was forwarded to the City Attorney’s Office, which has charged the man with 21 counts of third-degree malicious mischief. Another charge is expected after a business owner came forward this week to report his warehouse had also been tagged.
The 14-year-old boy is being held at Remann Hall Juvenile Detention Center.
Since the taggers kept hitting the same places, police scanned surveillance footage at some of the properties and found pictures of one of the taggers on a distinctive bicycle.
Officers spotted the bicycle outside a junior high school and traced it to one of the students, who allegedly admitted his involvement. The investigation led police to another 14-year-old boy and the 18-year-old man.
