Investigators said more than 20 vehicles have been keyed since June in Greenwich's Pemberwick Road area and a neighbor spotted Janina Slomiana keying a car Sunday morning, the same morning as five other reported incidents, the Greenwich Time reported Thursday.
Slomiana was arrested and charged with six counts of criminal mischief.
"The outstanding cases of the cars that have been vandalized are still under investigation," Greenwich Police Lt. Kraig Gray said. "At this point, we can't definitively trace them back [to Slomiana]."
Police said they have not yet determined a motive for the incidents.
